Hi Cisco Gurus,
I have to accommodate a core device, lets call it "bob" with two 7609 routers equipped with ES+ cards.
bob has two links towards each of the 7609's. I need to associate the bob interfaces on a vrf called bob_vrf.
Here is the tricky part:
Bob has a default to an HSRP address which i need to facilitate on the routers since there is no connectivity between the two links coming from bob. The 7609's also have a static route pointing to bob's vip address (vrrp).
I need to facilitate a link between the 7609's which will allow both the HSRP messages between the routers and VRRP messages from bob to be transported.
How would i do this? Im working with a single vlan 10. i need to somehow add a layer 2 inter router link between the 7609's to bridge traffic on this same vlan so gi1/1 from 7609 router 1 can reach gi1/1 on 7609 router 2. This bridge also needs to be associated with the bob vrf.
I have attached a diagram to highlight the issue and im hoping you might be able to help with a novel solution for this perhaps using service-instances and bridge domains.
ES card implements EVC (Ethernet Virtual Circuit) framework based on Metro Ethernet Forum specification. Now your VLAN id scope is limited to your port and there is no more default VLAN manipulation like you have with classical LAN LC. That's why you have to explicitly pop your VLAN ID before sending the packet to Layer 3 engine. The symmetrical keyword will add the VLAN ID back to the packet before sending it to the wire.
