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

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

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

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?

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
