Hi guys,
I have been simulating the attached scenario to get access to Internet following the way of HCDP-BITN book, Chapter 2 Internet Access via the MPLS VPN backbone pag. 227., but it works partially. PE1 interface connected to RTA is not bound to any VPN. PE1 and CE1, and PE2 and CE3 change routing information with RIP. PE1 and PE2 run MP-BGP. CE1 and CE3 belong to VPNA and they can ping each other successfully. CE1 can access the internet and can ping 8.8.8.8 (on INTERNET router) through gateway RTA successfully. However, CE3 can't ping 8.8.8.8. If I do tracert 8.8.8.8 on CE3 the trace gets stuck at PE2. Where could the problem be? I have made lots of changes but I cannot find the problem.
I have attached the device configurations and also the .topo file.
Please your help.
Thank you in advance,
Julián
