What’s Changed in Release 21.2R3-S1

Routing Protocols

  • When the krt-nexthop-ack statement is configured, the RPD waits for the next hop to get acknowledged by PFE before using it for a route. Currently, only BGP-labeled routes and RSVP routes support this statement. All other routes ignore this statement.

MPLS

  • The MPLS EXP bits transmitted in self ping messages are set based on the DSCP/ToS setting of the corresponding IP packet.
