Eigrp is down: retry limit exceeded
WebYes as long as this is IP communication there will be IP MTU limitations for the EIGRP packet ( mostly reflecting, L2 MTU limitations ) As long as you have DMVPN tunnels up that means the tunnel has the correct L2 MTU configuration across the path for EIGRP. WebEIGRP uses multicast (224.0.0.10) and its own transport protocol (88), but NAT does not work well with multicast, and it only works with TCP, UDP, and ICMP. If you need to use …
