I have two 7609-S boxes equipped with ESM20G cards and WS-X6748-GE-TX cards. A trunk is configured on ports of WS cards between these devices. A very important system is to be connected with two optical links to both devices via ES20 cards for redundancy. I consider configuring it using EVC framework in the following way:
service instance -> bridge-domain XXX -> interface VLAN XXX and enable HSRP on my devices.
I am not sure what is the structure of conecting system so I would like to have some kind of L2 connectivity between my devices for this connection. For other connections made using ports on WS card a dedicated VLAN is allocated for every one of them and then this VLAN is simply put in trunk between devices. Can I simply add vlan XXX to the list of VLANs allowed on the WS-card-based-trunk or do I have to utilize some completely different solution? Links to any related documentation are appreciated. Tomorrow I am going to test this configruation any way but I would like to have some backup solution in case this will not work.
Thanks in advance,
