High WAN RTT and OSPF

Unanswered Question
Aug 25th, 2008

Are there any special considerations when designing a WAN with OSPF that includes nodes that have RTT's around 200-300ms? Will that amount of delay cause issues?

Thanks,

I have this problem too.

In this case the high RTT is due to distance, New York - Hong Kong. I'm designing a new network with an OSPF core across a VPLS mesh network. I'll have sites in London, Hong Kong, and New York. Do you think this will cause any issues?

I usually use BGP for long distance, and use OSPF for short distance.

Since I have no working knowledge of BGP, I'm very very hesitant to try and implement that. I'm just curious if 200-300ms of latency between the two most distant nodes will cause any problems with OSPF.

Thanks again,
