Hi all,
I'm trying to redistribute BGP to EIGRP and vice versa. I am succussfully redistributing EIGRP to BGP, but can't get EIGRP routes into BGP.
Here's my config. Any guidance or assistance would be very much appreciated.
router eigrp 100
network 10.18.72.0 0.0.0.255
redistribute static route-map DEFAULT_ROUTE
redistribute bgp 65535
passive-interface default
no passive-interface FastEthernet0/0
!
router bgp 65535
bgp router-id 172.18.2.1
bgp log-neighbor-changes
redistribute eigrp 100 route-map EIGRP_REDISTRIBUTE
neighbor 172.18.2.2 remote-as 65535
neighbor 172.18.2.2 password ciscobgp
no auto-summary
ip access-list extended EIGRP_ROUTES_TO_BGP
permit ip any any
!
!
ip prefix-list DEFAULT seq 5 permit 0.0.0.0/0
!
route-map EIGRP_REDISTRIBUTE permit 20
match ip address EIGRP_ROUTES_TO_BGP
!
route-map DEFAULT_ROUTE permit 10
match ip address prefix-list DEFAULT
Thanks in advance.

Add "bgp redistribute-internal" to your bgp process. By default, iBGP doesn't redistribute into an IGP. The reason for this is simply the amount of routes that a bgp router can receive could overload an igp very easily, so you would definitely want to filter routes out when doing this.
After you add this, clear your bgp neighbors and you should start seeing routes.
HTH,
John

Hey Guys,
I think the problem is that you don't have a metric assigned to the redistribution statement under eigrp.
redistribute bgp 65535 metric 100000 500 255 1 1500
Thanks,
Mark

This is exactly what I needed.
Thank you!

Yep, adding the bgp redistribute-internal to the BGP config and redistribute bgp <AS_NUM> metric 100000 500 255 1 1500 to the EIGRP config sorted this out for me... so both of these answers combined from [@j.blakley] & makrez969 did the trick. Thanks!
