Hello all,
We are having problems with our slow OTV. The topology is setup as:
Main DC:::::::::::::Servers --> Nexus 5K --> ASR1K -----> (Core)---> (WAN)---->::::::::::::DR site::::::::::::::: ASR1K ---> Nexus5K ---> servers (for replication)
We have a 1 gig connection of WAN. but when our server group do replication the maximum speed is 60-70 Mbps on the WAN using the OTV link.
Other configurations are:
No Jumbo frames are allowed.
Fragmentation is allowed at the join interface of both the ASR because the of OTV header of 42 bytes.
We have full connectivity but the link is slow. What could be the possible solution?
Response will really appreciated.
Thanks

Hello, can you run ttcp along with iperf end to end and see what speeds you actually getting (not OTV but routed)
Then set your benchmark, OTV should not be extremely far off the actual speed. Please also make sure MTU is enough all the way from end to end WAN links.
