A question about mutual redistribution between EIGRP and BGP
hi: I setup a lab with 6 routers as you can see from the attachment, PE1 run IBGP with PE2, PE1 run EBGP with CE3, PE2 run eBGP with CE4, and CE3, CE4, R5 and R6 run EIGRP1. I configured mutual redistribution on CE3 and CE4 (take CE3 as example:)
router eigrp 1
redistribute bgp 200 metric 100000 100 255 1 1500
router bgp 200
network 220.127.116.11 mask 255.255.255.255
redistribute eigrp 1
neighbor 18.104.22.168 remote-as 500
and CE4 has the samiliar config except the IP address.
1. I know mutual redistribution is quite compilcated issue and it may creat routing loop, you need to use route-map to prevent routing loop, but after I config redistribution without route-map, I check every route, it looks fine, can I say it will not cause routing loop?
2. When I tried to add route-map on both CE3 and CE4 router, my solution is that:
but when I applied "redistribute eigrp 1 route-map b2e" I got warining msg:"% "b2e" used as redistribute eigrp into bgp route-map, set tag not supported". After that I tried to check the route tag, I found all the route learn by BGP has route tag:500, and I am not able to see the route tag leared by EIGRP?
