Hi, Looking for some advice / suggestions
Here's a diagram of two sites in a MAN - We're having a new WAN service delivered and opted to have one leg at two sites (there are 5 man sites) so if one site loses power, the whole MAN doesn't drop off the WAN. The 'internet' cloud should actually read 'SDWAN', but it's still an internet connection I guess.
Today the Vendor advises that both WAN routers (EC01 and EC02) need to create a couple of dot1q trunks between each other, not have a layer 3 relationship as we planned.
My first though is a BVI - or Bridge domain as they're now called.
interface GigabitEthernet0/0/1.100 (existing site to site link)
encapsulation dot1Q 100
Bridge-Domain 100
interface GigabitEthernet0/0/3.100 (unused interface, plug into EC)
encapsulation dot1Q 100
Bridge-Domain 100
Anyone used Bridge-Domains on C4431 routers? Thinks it'll work? Has a much better suggestion?
