What I did: Workaround for the issue seen here : FRRouting/frr#13682 It seems there is timing issue where there are multiple recursive lookup needed to resolve nexthop of the route it's possible that it does not happen correctly causing route to remain in inactive state Issue is seen on chassis-packet as there 2 level of recursive lookup needed for a given e-BGP learnt route - Level1 to resolve e-BGP peer (connected route via bgp ) over Loopback4096 (i-BGP peering) - Level 2 Loopback4096 over backend port-channels next-hops For VOQ chassis there is no e-BGP peer (connected route via bgp ) resolution as route is added as Static route by orchagent over Ethernet-IB. Also as part of this remove route-map policy from instance.conf.j2 as same is define in peer-group.j2. Microsoft ADO: https://msazure.visualstudio.com/One/_workitems/edit/24198507 How I verify: Functional Verification manually Updated UT. We will be adding sanity check in sonic-mgmt to make sure none of route are in inactive state. Signed-off-by: Abhishek Dosi <abdosi@microsoft.com>
