Please hepl me resolve this case.
We have DR distance from DC about 30km.
In DC, we have 2 Cisco Nexus 7K devices.
In DR, we have 2 Cisco Nexus 9K devices.
Between DC and DR, We have 2 DWDM connections.
Can you have a any solution to aggregate (vPC or any solution) 2 DWDM links ?
If you have solution, please give me configure example?
My topology is below,
Please help us, Thanks for your support
You can use Back to Back VPC, see the following example:
GTO, Montreal, Canada | CGI
5800, RUE ST-DENIS, 8E ÉTAGE (bureau 8.555)
T: 514-415-3000 #1018409
I would say it heavily depends on the requirements to the DR site and the switch models (line cards)? Are there a requirement for L2 between the sites or will L3 be just fine? I would always try go with L3 routing between sites to avoid L2 loops. If L2 is a requirement, then back-to-back VPC as Malik suggest will be a fine way to go.
