If the ARP request reaches A directly, A replies through the same port on which it learned S1's
MAC address.
If the request comes through B, S1's ARP response is learned on the ICL first and then it moves to
the CCEP link when the MDUP message for S1's MAC address is received from B.
VRRP or VRRP-E configuration with MCT
In the following figure, MCT devices A and B both need to ensure that packets sent to the VRRP-E
virtual IP address can be Layer 2-switched to the VRRP-E master router for routing. Both data traffic
and VRRP-E control traffic travel through the ICL, unless the short-path forwarding feature is enabled.
The VRRP or VRRE-E virtual MAC address is learned on ICL ports on backup routers through the ICL.
The VRRP or VRRP-E master router broadcasts hello packets to all VLAN member ports, including
ICL ports.
