The VRRP-E virtual MAC will be learned on backup routers through the ICL.

When the CEP or CCEP port goes down, traffic will be re-routed to pass through the ICL.

The VRRP-E master and the VRRP-E backup pass GRE traffic across the ICL.

The VRRP-E master router will broadcast hello packets to all VLAN member ports including ICL
ports.

OSPF configured on the CCEP ports will load balance the traffic between the VRRP-E peers.

Use Q-in-Q VLAN tagging to keep the customer’s VLANs intact.

Use GRE to create a VLAN tunnel through your service.

Have the customer(s) map their VLANs on each side of your Carrier Ethernet service.

Use DSCP to map the customer’s VLANs at the ingress and egress of your service.

You can restrict access from clients using IPv4 and IPv6 within the same ACL.

You must enable IPv6 before applying an ACL.

You need to explicitly permit IPv6 neighbor discovery acknowledgements.

You can apply IPv6 ACLs to allow user-based schemes.
