Hello experts
I have facing a problem on the redistribution
background
in my company mainly EIGRP, but recently we have 1 site setup VXLAN, so some of the Eigrp router they need to exchange the route will becomes EIGRP---> BGP ---> EIGRP but seems that is not possible to redistribute the "BGP, external metric " back to EIGRP. so I try to retain the TAG at least.
so my logic is:-
when EIGRP--> BGP
I will match the TAG 222/300/301 from EIGRP then convert to BGP community 999:222/300/301 (and default is 301)
when BGP--> EIGRP
I will match the Community 999:222/300/301 then convert to EIGRP Tag 222/300/301 (and default is 301) and hard code some metric
the problem is 2), the route map only fall to the last one permit-bgp-eigrp999 100
