Inconsistency in auto-derived RT value of EVPN show commands. #5605
FRR version: 7.0
For an RT-5 prefix received from an EBGP peer, FRR shows different RT values in the output of different commands. R1 is the advertising prefix 10.1.1.1 to router R2(which has 3 tenant VRFs.) Please refer below outputs for more details:
"sh bgp l2vpn evpn vni" shows that vrf RED imports prefixes with RT value 300:100
"sh bgp l2vpn evpn vrf-import-rt" shows that vrf RED imports prefixes with RT value 0:100
"sh bgp l2vpn evpn 10.1.1.1" shows that prefix 10.1.1.1 is received from peer router with RT value 100:100, yet it's imported in vrf RED.
To summarise this issue, R2 receives prefix 10.1.1.1 with RT value 100:100, VNI 100 is mapped to RT value 300:100, and evpn vrf-import-rt value shows 0:100. Yet the prefix is installed in tenant vrf on R2.
Please let me know if you need any further information from my end.
@rohitgeek Auto-derived RT is derived from
It is more of show command issue where it can be displayed (interpreted) as
@chiragshah6 : I agree with you. We may show "*" symbol for import RT(auto) values. For example:
