hello everyone,
I am trying to reach our server to the cloud on 10.65.120.0 network however I am not able to reach it via our remote offices. Though I am able to reach 10.65.1.0 network anywhere.
I noticed on the EIGRP topology, it does not include the 10.65.120.0 network. Is there anything I am missing on my network command? I tried to add 10.65.120.0/21 on EIGRP but no luck. I still cannot see the route from remote office.

I suppose the 10.65.0.0/19 should cover for all the subnets but it doesn't.

Hello @mudvayne15 ,
if the missing prefix 10.65.120.0/21 is learned in BGP you need to redistribute it into EIGRP
ip prefix-list BGP-ROUTE permit 10.65.120.0/21
route-map BGP-TO-EIGRP permit 10
match ip address prefix BGP-ROUTE
set metric 10000 100 255 1 1500
router eigrp 89
redistribute bgp <your-BGP-ASnumber> route-map BGP-TO-EIGRP
In EIGRP a seed metric is needed providing its components where the last one is the MTU.
This is done in the route-map alternatively you could set a default-metric at EIGRP process level.
Hope to help
Giuseppe

Hello @mudvayne15 ,
I'm happy it worked for you.
>> Though my other question is, why the other subnet 10.64.1.0 from BGP is reachable. Is it because of the static route 10.65.0.0/19 redistributed in EIGRP?
yes your understanding is correct that subnet 10.65.1.0 is covered by 10.65.0.0/19
Hope to help
Giuseppe
