· display ip routing-table ip-address longer-match

¡ The system ANDs the entered destination IP address with the subnet mask in the following way:

- If the entered IP address belongs to class A, B, or C, the system ANDs it with the default subnet mask of the corresponding class.

- If the entered IP address is 0.0.0.0, the system ANDs it with the subnet mask 0.0.0.0.

- Except the previous cases, for example, if the entered IP address is a multicast address or loopback address, the system ANDs it with the subnet mask 255.255.255.255.

¡ The system ANDs the destination IP address in each active route entry with the subnet mask of the entered IP address.

If the two operations yield the same result for multiple entries, all the entries are displayed.

· display ip routing-table ip-address mask longer-match

¡ The system ANDs the entered destination IP address with the entered subnet mask.

¡ The system ANDs the destination IP address in each active route entry with the entered subnet mask.

If the two operations yield the same result for multiple entries, all the entries are displayed.

· display ip routing-table ip-address1 to ip-address2

Table 5 Command output

Field	Description
Max ECMP	Maximum number of ECMP routes supported by the system.
Max Active Route	Maximum number of supported routes.
Remain Active Route	Number of the remaining inactive routes.
Threshold value xxx	Alarm threshold of active routes specified by using the routing-table limit command in a VPN instance: · Threshold value of active routes alert—This field is displayed when the alarm threshold is specified by using the routing-table limit number simply-alert command. When the number of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes. · Threshold value percentage of max active routes—This field is displayed when the alarm threshold is specified by using the routing-table limit number warn-threshold command, in the range of 1 to 100 in percentage. When the percentage of active routes exceeds the alarm threshold, the system logs the event and sends traps but still accepts active routes. If the number of active routes reaches the maximum number, no more routes can be added. The percentage of active routes equals the number of active routes divided by the maximum number of active routes supported in a VPN instance, and multiplied by 100.

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN instance by its name, a case-sensitive string of 1 to 31 characters. If you do not specify a VPN instance, the command enables IPv4 or IPv6 RIB inter-protocol FRR for the public network.

Usage guidelines

This command allows a device to perform fast rerouting between routes of different protocols. A backup next hop is automatically selected to reduce the service interruption time caused by unreachable next hops. When the next hop of the primary link fails, the traffic is redirected to the backup next hop.

This command uses the next hop of a route from a different protocol as the backup next hop for the faulty route, which might cause loops.

Inter-protocol FRR cannot select a backup next hop from routes in the RIB that have the same next hop, output interface, and destination as those of the faulty route.

Examples

# Enable IPv4 RIB inter-protocol FRR for the public network.

Parameters

clear-interval interval: Specifies the interval for clearing the recursion loop counter, in the range of 1 to 65535 seconds.

Usage guidelines

Recursion loop suppression enables the system to use a counter to record the number of route recursion failures. When the counter reaches 20, the system suppresses route recursion for a specified period of time. When the suppression time expires, the system resets the counter and disables route recursion suppression.

Usage guidelines

A recursion loop occurs when a route recurses to a related route that recurses back to the route. It causes a route recursion failure and further lookup for a related route. If recursion loop persists, continuous route flapping will cause high system resource consumption and CPU utilization.

This command enables the system to use a counter to record the number of route recursion failures. When the counter reaches 20, the system suppresses route recursion for a specified period of time to save system resources on the device.

Parameters

ctrl: Specifies the BFD control packet mode.

echo: Specifies the BFD echo packet mode.

inter-protocol-frr: Enables primary link availability detection for inter-protocol FRR.

protocol-ecmp protocol: Enables primary link availability detection for ECMP routes of a routing protocol. In RIB IPv4 address family view, the value for the protocol argument can be bgp, ospf, isis, or static. In RIB IPv6 address family view, the value for the protocol argument can be bgp4+, ospfv3, isisv6, or static.

Usage guidelines

This command enables the device to use a BFD session to detect the next hop availability of the primary link.

· For inter-protocol FRR, the primary link is the route with the highest preference among the routes to the same destination.

· For ECMP routes of a routing protocol, the primary link is each ECMP route. If you specify the ecmp-shared keyword when configuring FFR for a routing protocol, the device will use the LFA algorithm to calculate backup next hops for each ECMP route. The routes destined for the backup next hops are also added to the routing table as ECMP routes and the state of these routes is backup. BFD does not detect these backup ECMP routes.

You can execute this command multiple times to change the BFD mode (echo packet mode or control packet mode).

If you do not specify the inter-protocol-frr or protocol-ecmp keyword, the command applies to both inter-protocol FRR and ECMP routes. The command without the inter-protocol-frr and protocol-ecmp keywords takes precedence over that with the inter-protocol-frr or protocol-ecmp keyword.

Parameters

protocol: Specifies a routing protocol, which can be bgp or static in RIB IPv4 address family view or bgp4+ in RIB IPv6 address family view.

route-policy-name: Specifies a routing policy by its name, a case-sensitive string of 1 to 63 characters.

Usage guidelines

Configure routing policy-based recursive lookup to control route recursion results. For example, when a route changes, the routing protocol has to perform a route recursion if the next hop is indirectly connected. The routing protocol might select an incorrect path, which can cause traffic loss. To prevent this problem, you can use a routing policy to filter out incorrect routes. The routes that pass the filtering of the routing policy will be used for route recursion.

The apply clauses in the specified routing policy cannot take effect.

Make sure a minimum of one related route can match the routing policy for correct traffic forwarding.

The routing policy does not apply to routes received from directly connected BGP neighbors.

Examples

# Configure recursive lookup based on routing policy policy1 for BGP routes.

Parameters

track-entry-number: Specifies a track entry ID in the range of 1 to 1024.

degrade-cost cost-value: Specifies a cost value to apply to the direct route after the track entry changes to Negative state. The value range for the cost-value argument is 1 to 4294967295.

Usage guidelines

On a network where a VRRP group is used as the default gateway, upstream traffic is always forwarded through the master device in the VRRP group. The corresponding downstream traffic might take a different path because the route selection is determined by the configured dynamic routing protocol. The mismatching forwarding paths might cause the traffic to be blocked by firewalls (if configured), and increase the complexity and overhead for traffic monitoring and statistics collection operations.

You can resolve the issue by configuring direct route-Track-VRRP collaboration. The collaboration ensures that the upstream traffic and the corresponding downstream traffic are forwarded through matching paths (both through the master device in the VRRP group).

To configure direct route-Track-VRRP collaboration, perform the following tasks on each member device of the VRRP group:

1. Create a track entry associated with the VRRP group member device so the track entry state changes according to the status of the device in the VRRP group.

¡ If the device state is Backup or Initialize, the track entry state changes to Negative.

¡ If the device state is Master, the track entry state changes to Positive.

¡ If the device state is Inactive or the VRRP group does not exist, the track entry state changes to NotReady.

2. Associate the track entry with the direct route on the interface connected to the downstream device. The cost value of the direct route on the interface changes according to the status of the track entry.

¡ If the track entry does not exist or the track entry is in NotReady or Positive state, the cost of the direct route changes to 0.

¡ If the track entry is in Negative state, the cost of the direct route changes to the value configured by using the route-direct track command.

IMPORTANT:

The direct route that has a lower cost value is preferentially used.

3. Enable direct route redistribution on the VRRP group member device for the dynamic routing protocol.

The direct route on an interface can be associated only with one track entry. To change the track entry associated with the direct route on an interface, you must first execute the undo route-direct track command to remove the original association.

Examples

# Associate track entry 1 with the direct route on VLAN-interface 2 and apply cost 200 to the direct route after the track entry changes to Negative state.
