Hi,
I have two cedge router and I have configured VRRP in the service VPN (VRF 1) but the VRRP state of two router is master. I have pasted the configuration in below.
Router1:
interface Vlan101
vrf forwarding 1
ip address 10.1.1.2 255.255.255.0
no ip redirects
ip tcp adjust-mss 1430
vrrp 101 address-family ipv4
priority 105
vrrpv2
address 10.1.1.1 primary
exit-vrrp
arp timeout 1200
!
Router2:
interface Vlan101
vrf forwarding 1
ip address 10.1.1.3 255.255.255.0
no ip redirects
ip tcp adjust-mss 1430
vrrp 101 address-family ipv4
priority 90
vrrpv2
address 10.1.1.1 primary
exit-vrrp
arp timeout 1200
in Below you can see the result of show vrrp brief command:
Router1: show vrrp brief
Interface Grp A-F Pri Time Own Pre State Master addr/Group addr
Vl101 101 IPv4 105 0 N Y MASTER 10.1.1.2(local) 10.1.1.1
Router2: show vrrp brief
Interface Grp A-F Pri Time Own Pre State Master addr/Group addr
Vl101 101 IPv4 90 0 N Y MASTER 10.1.1.3(local) 10.1.1.1
Please help me to solve this problem

I found the problem. Behind these two routers is an old non-Cisco switch. I deactivated the 'Unknown Multicast No Flood' feature in this switch, and the problem has been solved.

Hi Hamidreza,
Do you have connectivity between both VLANs?
How do you interconnect both routers, do you have a Core switch?

Maybe, It could be a typo, but you are showing us Vlan1 configuration, but on the sh vrrp br you hace Vlan101 as active on both WAN Edge.

I rectified that. Thanks

Yes, I can ping the physical IP address from each router to the other router.

1. Can router1 and router2 communicate each other? ICMP?
2. Is multicast between routers permitted?

Yes, I can ping , the ICMP goes between the two router.
There is an old (non-Cisco) switch between the two routers. I have doubts that the old switch does not support protocol 112 or Multicast. I must more investigate about these unknown old switches

Have you tried pinging 224.0.0.18?

show vrrp <<- can I see this from cedge
also can I see
show interface trunk <<- from C9K
and
show vlan brief <<- from C9K
MHM
