Redistributing eigrp into bgp

I currently have a mpls wan with eigrp internal. Can someone post a simple config of redistributing eigrp into bgp with route-map for specfic routes to be redistributed.

thanks...

Hi there

You could use

router bgp 65000

redistribute eigrp 65432 route-map EIGRP2BGP

router eigrp 65432

redistribute bgp 65000 route-map bgp2eigrp

route-map EIGRP2BGP permit 10

match ip address prefix-list 90

route-map bgp2eigrp permit 10

match ip address prefix-list 100

set metric 1 2 3 4 5

ip prefix-list 90 permit 10.234.0.0/16 le 32

ip prefix-list 100 permit 10.1.0.0/16 le 32

Modify the prefix-lists to your needs.

Hope this helps

Re: Redistributing eigrp into bgp

Thanks for the reply. If i just need eigrp to bgp i would use the following commands:

router bgp 65000

redistribute eigrp 65432 route-map EIGRP2BGP

route-map EIGRP2BGP permit 10

match ip address prefix-list 90

ip prefix-list 90 permit 10.234.0.0/16 le 32

Dont i also need the routing metric commands???

thanks

Re: Redistributing eigrp into bgp

Hi,

to redistribute EIGRP into BGP you need no metric commands. The BGP attribute MED (metric) will be set to the eigrp metric in the routing table automatically.

Hope this helps

Re: Redistributing eigrp into bgp

I have a question for you...

In the MPLS cloud your routes are learnt via BGP. Why u want filter MPLS - BGP routes getting redistributed in to EIGRP?

Re: Redistributing eigrp into bgp

Hi,

mutual redistribution in several poinnts for redundancy can easily result in routing loops. So learning through BGP on one router in a location what you told BGP on the other router in the same location is not a good idea.

The second issue would be protection from SP misconfiguration. Don´t let him insert stuff that you are sure could never be there.

In both cases BGP2EIGRP filters could be handy.

Hope this helps

Martin
