Re: VRRP over IRB - can't ping L3 interfaces

Hi,

You can read the below document.

https://www.juniper.net/documentation/en_US/junos/information-products/pathway-pages/mc-lag/multichassis-link-aggregation-groups.html

Routing protocols run on the primary IP address of the IRB or RVI interface, and both of the MC-LAG peers run routing protocols independently. The routing protocols use the primary IP address of the IRB or RVI interface and the IRB or RVI MAC address to communicate with the MC-LAG peers. The IRB or RVI MAC address of each MC-LAG peer is replicated on the other MC-LAG peer and is installed as a MAC address that has been learned on the ICL.

Note: If you are using the VRRP over IRB or RVI method to enable Layer 3 functionality, you must configure static ARP entries for the IRB or RVI interface of the remote MC-LAG peer to allow routing protocols to run over the IRB or RVI interfaces.
