In bgp route leak, when import vrf x is executed,
it creates bgp instance as hidden with asn value as unspecified.
When router bgp x is configured ensure the correct as,
asnotation is applied otherwise running config shows asn value as 0.
This can lead to frr-reload failure when any FRR config change.
Fix:
Move asn and asnotiation, as_pretty value in common done section,
so when bgp_create gets existing instance but before returning
update asn and required fields in common section.
In bgp_create(): when returning for hidden at least update asn
and required when bgp instance created implicitly due to vrf leak.
if (hidden) {
bgp = bgp_old;
goto peer_init; <<<
}
Before fix:
show running:
router bgp 0 vrf purple
bgp router-id 10.10.3.11
!
address-family ipv4 unicast
redistribute static
import vrf blue
exit-address-family
!
address-family ipv6 unicast
import vrf blue
exit-address-family
!
address-family l2vpn evpn
advertise ipv4 unicast
advertise ipv6 unicast
exit-address-family
exit
Testing:
1) following snippet config:
router bgp 63420 vrf blue
import vrf purple
router bgp 63420 vrf purple
import vrf blue
2) restart frr leads to the running config with 0 asn value.
