Full internet routing in an internet MPLS VPN

Is it possible and advisable to run the full internet routing table in a seperate MPLS VRF. A default route is not an option

With kind regards,

Mike

Re: Full internet routing in an internet MPLS VPN

Hi,

It is not advisable to have full Internet Routing table in a vrf.It is possible that you may run out of memory since different routers have different vrf routes holding capacity.e.g if you are using 12000 series and you have only one vrf configured then you can hold the entire Internet routing table in one vrf.

Which router you have ? Is it 12000 ?How many vrfs you have ? How many routes have you per vrf ?

You need to consider the above questions before making the decision.

Hi,

The routers we use are the 12000 serie. Is there a list for the different platforms and there routes holding capacity per vrf.

Up to 200 VRF but only with a default route,

and one VRF with the full internet routes.

Hi Mike,

Its very hard to come up with the list since vrf route capacity has number of variables like number of vrfs,line card engine,presence of other features like ACl etc.

Which line card engine you have ?

If its engine 2 or 3 then you can use the full internet routing table since you have 200 vrfs but with default route.

If its engine 2 and you are not using ACLs then you can disable them to get more vrf routes.
