Mpls pe/ce

Hi Rene,

I should say that your site really helped me a lot in getting my CCNP. Big Thanks!
Regarding the lab above, i am just quite puzzled why I am unable to ping CE2 ( from CE1 (

I checked thoroughly the configs and it seems no difference
Below is my routing table from my PE1 and could see that i could reach via my GRE Tunnel although when i checked the CEF Table it still goes to my P router.

Gateway of last resort is not set

Hi Eleever,

Good to hear my work has been useful to you :slight_smile:

Your PE1 router is using as the next hop for is reached by using as the next hop, that’s your P router.

You need to make sure that your PE1 (and PE2) router prefers to use the tunnel interface. You could do this by playing with the metric, administrative distance or filtering.
