Description
Use the cache-sa-enable command to enable the SA cache mechanism to cache the (S, G) entries contained in SA messages.
Use the undo cache-sa-enable command to disable the SA cache mechanism.
By default, the SA cache mechanism is enabled, that is, the device caches the (S, G) entries contained in SA messages received.

Default Level
2: System level
Parameters
Description
Use the encap-data-enable command to enable register message encapsulation in SA messages.
Use the undo encap-data-enable command to disable register message encapsulation in SA messages.
By default, an SA message contains only an (S, G) entry. No register message is encapsulated in an SA message.

import-source
Syntax
import-source [ acl acl-number ]
undo import-source
View
Public instance MSDP view, VPN instance MSDP view
Default Level
2: System level
Parameters
acl-number: Basic or advanced ACL number, in the range of 2000 to 3999. A basic ACL is used to filter multicast sources, while an advanced ACL is used to filter multicast sources or multicast groups. If you do not provide this argument in your command, no multicast source information will be advertised.
During ACL matching, the protocol ID in the ACL rule is not checked.
Description
Use the import-source command to configure a rule of creating (S, G) entries.
Use the undo import-source command to remove any rule of creating (S, G) entries.
By default, when an SA message is created, there are no restrictions on the (S, G) entries to be advertised in it, namely all the (S, G) entries within the domain are advertised in the SA message.
In addition to controlling SA message creation by using this command, you can also configure a filtering rule for forwarding and receiving SA messages by using the peer sa-policy command.
Related commands: peer sa-policy.
Examples
# Configure the MSDP peer in the public instance to advertise only the (S, G) entries of multicast sources on the 10.10.0.0/16 subnet and with multicast group address of 225.1.0.0/16 when creating an SA message.

Use the reset msdp peer command to reset the TCP connection with the specified MSDP peer or the TCP connections with all MSDP peers and clear all the statistics information of the MSDP peer(s).
Note that if neither all-instance nor vpn-instance is specified, this command will display the information on the public instance.
Related commands: display msdp peer-status.
Examples
# Reset the TCP connection in the public instance with the MSDP peer 125.10.7.6 and clear all the statistics information of this MSDP peer.
<Sysname> reset msdp peer 125.10.7.6

Default Level
2: System level
Parameters
all-instance: Specifies all instances.
vpn-instance vpn-instance-name: Specifies a VPN instance. A VPN instance name is a case sensitive string of up to 31 characters and must not contain any space.
group-address: Specifies a multicast group, in the range of 224.0.1.0 to 239.255.255.255. If you do not provide this argument, the command will clear the cached (S, G) entries for all multicast groups from the SA cache.
Description
Use the reset msdp sa-cache command to clear (S, G) entries from the SA cache.
Note that if neither all-instance nor vpn-instance is specified, this command will clear the information on the public instance.

Parameters
all-instance: Specifies all instances.
vpn-instance vpn-instance-name: Specifies a VPN instance. A VPN instance name is a case sensitive string of up to 31 characters and must not contain any space.
peer-address: Address of the MSDP peer of which the statistics information is to be cleared. If you do not provide this argument, the command will clear the statistics information of all MSDP peers.
Description
Use the reset msdp statistics command to clear the statistics information of the specified MSDP peer or all MSDP peers without resetting the MSDP peer(s).
Note that if neither all-instance nor vpn-instance is specified, this command will clear the information on the public instance.
Examples
# Clear the statistics information of the MSDP peer 125.10.7.6 in the public instance.
<Sysname> reset msdp statistics 125.10.7.6
shutdown (MSDP View)
Syntax

Default Level
2: System level
Parameters
peer-address: MSDP peer address.
Description
Use the shutdown command to deactivate manually the connection with the specified MSDP peer.
Use the undo shutdown command to reactivate the connection with the specified MSDP peer.
By default, the connections with all MSDP peers are active.
Related commands: display msdp peer-status.
Examples
# Deactivate the connection with the MSDP peer 125.10.7.6 in the public instance.

static-rpf-peer
Syntax
static-rpf-peer peer-address [ rp-policy ip-prefix-name ]
undo static-rpf-peer peer-address
View
Public instance MSDP view, VPN instance MSDP view
Default Level
2: System level
Parameters
peer-address: MSDP peer address.
rp-policy ip-prefix-name: Specifies a filtering policy based on the RP address in SA messages, where ip-prefix-name is the filtering policy name, a case sensitive string of 1 to 19 characters. A policy name must not contain any space.
Description
Use the static-rpf-peer command to configure a static RPF peer.
Use the undo static-rpf-peer command to remove a static RPF peer.
No static RPF peer is configured by default.
When you configure multiple static RPF peers, observe the follow rules:
1) If you use the rp-policy keyword for all the static RPF peers, all the static RPF peers take effect concurrently. SA messages will be filtered as per the configured prefix list and only those SA messages whose RP addresses pass the filtering will be accepted. If multiple static RPF peers use the same filtering policy at the same time, when a peer receives an SA message, it will forward the SA message to the other peers.
2) If you use the rp-policy keyword for none of the static RPF peers, according to the configuration sequence, only the first static RPF peer whose connection is in the UP state will be activated, and all SA messages from this peer will be accepted while the SA messages from other static RPF peers will be discarded. When this active static RPF peer fails (for example, when the configuration is removed or when the connection is torn down), still the first RPF peer whose connection is in UP state will be selected as the activated RPF peer according to the configuration sequence.
