forwarding-table

Syntax

Hierarchy Level

Description

Configure information about the routing device’s forwarding table.

Some of the remaining statements are explained separately. See CLI Explorer.

Options

evpn-egress-link-protection

Enables multihomed PE devices to support fast reroutes (FFRs).
multicast-composite-delete-defer-timeout

Use this command to delay the deletion of a composite next-hop from the FIB (in the event of dropped multicast packets following a downstream interface change). You can view the set time by running the show krt state command.

Range: 1 to 3600 seconds
pfe-install-error

(Junos OS Evolved only) Enable error checking for Packet Forwarding Engine route install errors. When configured, the forwarding plane can inform the control plane of any errors in next hops. ​If a route error is received from the Packet Forwarding Engine, the route error is directly added to the route-error list. For next-hop errors, the error is propagated to the parent route and the parent route is added to the route-error list. Two commands are available to check on these route errors after you have configured this feature:

  • If the forwarding plane is not forwarding traffic, use the show route pfe-install-error command to ​check if the Packet Forwarding Engine has sent an error for the route that is dropping traffic​.

  • To check for next-hop errors, use the show routing nhdb pfe-install-error command. We support errors for routes pointing to a limited set of next hops: RT_NH_INDIRECT, RT_NH_ROUTER, RT_NH_CHAIN, RT_NH_INDXD, RT_NH_LIST, RT_NH_TUNNEL_COMP, and RT_NH_FRR_INDIRECT​.

remnant-holdtime

Sets the remnant hold time, which is required for the MXVC-ISSU, where the recommended value is 900.

  • Default: 180 (For all Junos OS releases and all Junos OS Evolved releases earlier than 20.4R2)

  • Default: 300 (For all Junos OS Evolved Release 20.4R2 and later)

route-origin-proto-tlv Configure this option to include the origin protocol information in route messages. The origin protocol is the protocol from which the route entry is learned.
srv6-chain-merge Enable merging of SRv6 chain nexthops.
vpls-hotstandby-convergence

Enabled on spoke devices to support sending different advertising labels on the active and standby pseudowires.

Required Privilege Level
