Pseudowire and HTTPS Problem

[wojciechlubas]

Hello,

I have 2 Core ASR9k connected back to back. There are VRRP Groups on some VLANs.

Right now I move VLANs from EFC to pseudowire links. PW is up and running, but I noticed, that since traffic have to go through PW, there are some issues with HTTPS/TLS connections. 

TLS goes through handshake, but as far tunnel is ready to be established, there is no communication. When I move back on old configuration, HTTPS works.

I have increased MTU to 1900, and compared on Wireshark the handshake, but packets are in normal size, there is no fragmentation or something.

Only secured traffic is affected.

What else could I check?

Thanks,

Wojtek

OK, solved :)

Just forgot, about increase MTU also on L3 interface.

Great! just be careful, is different if you are using brige domains, than if you are using p2p xc Good luck!
