undo aggregate ipv6-address prefix-length
View
IPv6 MBGP address family view
Default level
2 System level
Parameters
ipv6-address: Summary address.
prefix-length: Length of summary route mask, in the range 0 to 128.
as-set: Creates a summary with AS set.
attribute-policy route-policy-name: Sets the attributes of the summary route according to the routing policy. The routing policy name is a case-sensitive string of 1 to 63 characters.
detail-suppressed: Only advertises the summary route.
suppress-policy route-policy-name: Suppresses specific routes defined in the routing policy. The routing policy name is a case-sensitive string of 1 to 63 characters.
origin-policy route-policy-name: References the routing policy to specify routes for summarization. The routing policy name is a case-sensitive string of 1 to 63 characters.
The keywords of the command are described as follows:
Table 1 Functions of the keywords
Keywords |
Function |
as-set |
Used to create a summary route, whose AS path contains the AS path information of summarized routes. Use this keyword carefully when many AS paths need to be summarized, because the frequent changes of these specific routes might lead to route oscillation. |
detail-suppressed |
This keyword does not suppress the summary route, but it suppresses the advertisement of all the more specific routes. To summarize only some specific routes, use the peer filter-policy command. |
suppress-policy |
Used to create a summary route and suppress the advertisement of some summarized routes. If you want to suppress some routes selectively and leave other routes still advertised, use the if-match clause of the route-policy command. |
origin-policy |
Selects only routes satisfying the routing policy for route summarization. |
attribute-policy |
Sets attributes except the AS-PATH attribute for the summary route. The same work can be done by using the peer route-policy command. |
Description
Use the aggregate command to create an IPv6 summary route in the IPv6 MBGP routing table.
Use the undo aggregate command to remove an IPv6 summary route.
By default, no summary route is configured.
Examples
# In IPv6 MBGP address family view, create a summary of 12::/64 in the IPv6 MBGP routing table.

Default level
2: System level
Parameters
number: Number of IPv6 MBGP routes for load balancing. The value ranges from 1 to 16. When it is set to 1, load balancing is disabled.
Description
Use the balance command to configure the number of IPv6 MBGP routes used for load balancing.
Use the undo balance command to disable load balancing.
By default, load balancing is disabled.
Unlike IGP, IPv6 MBGP has no explicit metric for making load balancing decisions. Instead, it implements load balancing by using IPv6 MBGP route selection rules.
Related commands: display ipv6 multicast routing-table.

Parameters
value: Default local preference, in the range 0 to 4294967295. The larger the value is, the higher the preference is.
Description
Use the default local-preference command to configure the default local preference.
Use the undo default local-preference command to restore the default.
By default, the default local preference is 100.
Using this command can affect IPv6 MBGP route selection.
Examples
# In IPv6 MBGP address family view, set the default local preference to 180.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family multicast

default med (IPv6 MBGP address family view)
Syntax
default med med-value
undo default med
View
IPv6 MBGP address family view
Default level
2: System level
Parameters
med-value: Default MED value, in the range 0 to 4294967295.
Description
Use the default med command to specify the default MED value.
Use the undo default med command to restore the default.
By default, the default med-value is 0.
The multi-exit discriminator (MED) is an external metric of a route. Different from the local preference, the MED is exchanged between ASs and will stay in the AS once it enters the AS. The route with a lower MED is preferred. When a router running BGP obtains several routes with an identical destination but different next-hops from various external peers, it will select the best route depending on the MED value. In the case that all the other conditions are the same, the system selects the route with the lowest MED as the best external route.
Examples
# Devices A and B belong to AS100 and device C belongs to AS200. C is the peer of A and B. Configure the MED of A as 25 to make C select the path from B.

Parameters
ipv6-address: IPv6 address prefix.
prefix-length: Prefix length of the IPv6 address, in the range 0 to 128.
short-cut: If the keyword is specified for an IPv6 multicast eBGP route, the route will use the local preference rather than its own preference, and therefore it will hardly become the optimal route.
route-policy-name: Name of a routing policy, a case-sensitive string of 1 to 63 characters.
Description
Use the network command to inject a network to the IPv6 MBGP routing table.
Use the undo network command to remove a network from the routing table.
By default, no network is injected.
The network to be injected must exist in the local IPv6 routing table. You can use a routing policy to control the advertisement of the route with more flexibility.
The route injected with the network command has the IGP origin attribute.
Examples
# inject the network 2002::/16.

Parameters
group-name: Name of a peer group, a string of 1 to 47 characters.
ipv6-address: IPv6 address of a peer.
both: Supports sending and receiving route-refresh messages carrying the ORF information.
receive: Supports receiving route-refresh messages carrying the ORF information.
send: Supports sending route-refresh messages carrying the ORF information.
Description
Use the peer capability-advertise orf command to enable the ORF capability for a BGP peer or peer group.
Use the undo peer capability-advertise orf command to disable the ORF capability for the BGP peer or peer group.
By default, the ORF capability is not enabled for a BGP peer or peer group.
· After you enable the ORF capability, the local BGP router negotiates the ORF capability with the BGP peer through Open messages. After that, the BGP router can process route-refresh messages carrying the standard ORF information from the peer or send route-refresh messages carrying the standard ORF information to the peer. For non-standard ORF capability negotiation, you need also to configure the peer capability-advertise orf non-standard command.
· After you disable the ORF capability, the local BGP router does not negotiate the ORF capability with the specified peer or peer group.

Parameters
ipv6-group-name: Name of an IPv6 MBGP peer group, a string of 1 to 47 characters.
ipv6-address: IPv6 address of an IPv6 MBGP peer.
value: Preferred value, in the range 0 to 65535.
Description
Use the peer preferred-value command to assign a preferred value to routes received from an IPv6 MBGP peer or peer group.
Use the undo peer preferred-value command to restore the default.
The preferred value defaults to 0.
Routes learned from peers each have a preferred value. Among multiple routes to the same destination, the route with the greatest preferred value is selected.
If you both reference a routing policy and use the peer { ipv6-group-name | ipv6-address } preferred-value value command to set a preferred value for routes from a peer, the routing policy sets the specified preferred value for routes matching it. Other routes not matching the routing policy uses the value set with the peer preferred-value command. If the preferred value specified in the routing policy is zero, the routes matching it will also use the value set with the peer preferred-value command. For how to use a routing policy to set a preferred value, see the command peer { group-name | ipv6-address } route-policy route-policy-name { import | export } in this document, and the command apply preferred-value preferred-value in Layer 3—IP Routing Command Reference.

refresh bgp ipv6 multicast
Syntax
refresh bgp ipv6 multicast { ipv6-address | all | external | group ipv6-group-name | internal } { export | import }
View
User view
Default level
1: Monitor level
Parameters
ipv6-address: Soft-resets the connection to the specified IPv6 MBGP peer.
all: Soft-resets all IPv6 MBGP connections.
external: Soft-resets IPv6 multicast eBGP connections.
group ipv6-group-name: Soft-resets connections to an IPv6 multicast peer group. The name of the peer group is a string of 1 to 47 characters.
internal: Soft-resets IPv6 multicast iBGP connections.
export: Performs soft-reset in outbound direction.
import: Performs soft-reset in inbound direction.
Description
Use the refresh bgp ipv6 multicast command to soft-reset specified IPv6 MBGP connections. With this feature, you can refresh the IPv6 MBGP routing table and apply a new policy without terminating IPv6 MBGP connections.
To perform IPv6 MBGP soft-reset, all routers in the network should support route-refresh. If a peer not supporting route refresh exists in the network, you need to use the peer keep-all-routes command on the local router to save all route updates from the peer before performing soft reset.
Examples
# Soft-reset inbound IPv6 MBGP connections.
<Sysname> refresh bgp ipv6 multicast all import

flap-info: Clears routing flap information.
all: Resets all IPv6 MBGP connections.
group ipv6-group-name: Resets the connections to the specified IPv6 MBGP peer group.
external: Resets all the IPv6 multicast eBGP connections.
internal: Resets all the IPv6 multicast iBGP connections.
Description
Use the reset bgp ipv6 multicast command to reset specified IPv6 MBGP connections to reconnect to the peers.
Examples

Parameters
ipv6-address: Destination IPv6 address..
prefix-length: Prefix length of the IPv6 address, in the range 0 to 128.
Description
Use the reset bgp ipv6 multicast dampening command to clear route dampening information and release suppressed routes.
If no ipv6-address prefix-length is specified, all IPv6 MBGP route dampening information will be cleared.
Examples
# Clear the damping information of the route 2345::/64 and release the suppressed route.
<Sysname> reset bgp ipv6 multicast dampening 2345::64
reset bgp ipv6 multicast flap-info

1: Monitor level
Parameters
ipv6-address: Clears the routing flap statistics for the specified IPv6 address.
prefix-length: Prefix length of the IPv6 address, in the range 1 to 128.
as-path-regexp: Clears the routing flap statistics for routes matching the AS path regular expression.
as-path-acl-number: Clears the routing flap statistics for routes matching the AS path ACL. The value of this argument is in the range of 1 to 256.
Description
Use the reset bgp ipv6 multicast flap-info command to clear IPv6 MBGP routing flap statistics.
If no parameters are specified, the flap statistics of all the routes will be cleared
