Setup : Two routers 1 and 2 with frr installed and vrrp enabled bgp configured, one acting as master and other as backup.
Third router has bgp configured with frr,
Followed steps in the document to create macvlan device on router with vrrp configuration
The master vrrp router is not able to establish, bgp peering with the router which has bgp with frr installed.
Instead of communicating with macvlan interface, it is communicating with primary ip address eth1 interface.
See the following error in logs
192.168.58.115 connection rejected(VRF default:1234:default) - not configured and not valid for dynamic
Version
7.5.1-1.1+deb11u2
How to reproduce
Create 3 debian machines, with frr installed.
Configure 2 machines with vrrp master, backup and bgp installed.
Configure the third machine with vip configured in step 2 as bgp neighbor. and configure the vrrp master/backup with third machines ip as bgp neighbor
The master vrrp and third machine should connect via BGP and listed as neigbors. if the master is shutdown, the back should resume as master and get connected to third machine via BGP as neighbor.
Expected behavior
Master should form bgp peering with third router with vrrp vip
Actual behavior
Communication is happening through interfaces primary ip not the vip.
Configuration of router 1 and 2 (vrrp master/backup)
router 1 ip 192.168.58.115
router 2 ip 192.168.58.111
router 3 ip 192.168.58.12
vrrp ip 192.168.58.2

Additional context
Same configuration works with vrrp failover using keepalived and bgp with only frr
