IPSEC/GETVPN over MPLS

Ciscospy

Dear Sir

 

I am planning to use IPSEC over MPLS. Is there any sort of dependency on PE router or on Provider for configuring the IPSEC/GETVPN between CPE routers. 

 

Please answer. I am waiting.

Hello,

 

not that I know of. Most customers require IPSec VPNs, so ISPs usually accommodate for that.

Hello,

there is no dependency from the PE nodes if you want to use IPSEC or GETVPN between your CE nodes.

 

The MPLS service provider gives you L3 connectivity between sites.

The only recommendation is to ask for an increased MTU to take in account the overhead of IPSEC or GETVPN on the links between PE-CE.

This is for avoiding fragmentation issues.

From a technical point of view this is the only parameter to ask to the MPLS provider.

 

Hope to help

Giuseppe
