Hello group,
Based on the official document called “OTV Technology Introduction and Deployment Considerations”, I arrived to the four options in the diagram:
Now I want to find the pros and cons of each option. Right now I just have these:
1) OTV on-a-stick VDC can be removed in the future when the OTV and SVI routing can interoperate in the same VDC.
2) OTV inline makes more sense when you have a dedicated link for OTV.
3) dual-homed is better than single-homed since it offers more resiliency.
…
Anything else ? What option do you guys prefer ? I just have experience with OTV on-a-stick single-homed but without redundancy (two N7Ks in each site but just one doing OTV).
Another doubt I have in terms of OTV deployment: multicast mode or unicast mode ?
1) multicast requires an IP multicast aware core.
2) unicast doesn’t require IP multicast aware core.
3) troubleshooting is easier with unicast (?).
…
Thanks.
