Routing Protocols

Support for BGP route advertisement based on Packet Forwarding Engine acknowledgement (QFX5130-32CD and QFX5700)—Starting in Junos OS Evolved Release 22.1R1, you can enable BGP to advertise routes only if the route version installed in the Routing Engine matches the route version installed in the Packet Forwarding Engine. If a mismatch occurs, then BGP withdraws the route from the forwarding path and stops advertising the route. You can enable this feature by including the
request-long-lived-ack
and thesend-withdrawal-on-route-change
configuration statements at the [edit policy-options policy-statement policy-name then
] hierarchy level.[See Advertising BGP Routes Based on Packet Forwarding Engine.]
