Tunnel MTU

[richard.gosling]

Hi All,

I have a Router running 12.4

I have configured ip mtu 1300 but when I show int it says 1500 ??

Anyone aware of any bugs?

Thanks

Hi Richard,

Can you check the output of sh ip int tunnel x instead of sh int tunnel?

Does it shows correct or 1500??

If not showing correct, Can you post the output of below:
Sh run int tunnel x
And sh run int for physical interface sourcing the tunnel.
Also sh ip int tunnel x
