eBGP Multihoop

[syedasimtaqvi]

Hi, I am facing an issue over running e-bgp multi hoop. 

My router are advertising and my neighbors are up but my traffic is not floating and I am unable to ping advertised networks.

My end to end routers have hoop of almost 5 routers. WAN to wan connections are reachable over multi hoop and pingable as well.

Similar case is given below,

but is  their any other solution than GRE ?.

Hi

As long as the intermediary devices don't know your internal routing table there is no other way to do this than tunnelling.
GRE i not the only solution you could use an IPinIP to cut down on the headers.

Thanks rasmus,

Can you provide a template or some helping example to implement.  IPinIP ?

Hi

Here you go: https://www.cisco.com/c/en/us/td/docs/routers/asr9000/software/asr9k_r5-3/lxvpn/configuration/guide/b-l3vpn-cg53xasr9k/Concept.pdf
As far as i rememeber you just configure the tunnel mode to ipv4.
