compression header ip rtp

Answered Question
Jan 23rd, 2009

I tryed to configure rtp header compression in the policy attached to FastEthernet and failed-

Col(config-pmap-c)#compression header ip rtp

%FastEthernet0/0 does not support IP header-compression

Why it is so?

I have this problem too.

With native encapsulation, nothing.

In theory you could run a VPN between routers, and run compressed IPsec on it to gain LZH compression (cRTP doesn't work with ipsec), but it seems an overkill.

Hope this helps, please rate post if it does!

Because cRTP is not supported on ethernet - there is no standard for that.
