Two routers, R1 and R2, have established an EIGRP neighbor relationship, but there is still a connectivity problem. Which issue could be causing this problem?
- an access list that is blocking advertisements from other networks
- an authentication mismatch
- automatic summarization that is disabled on both routers
- a process ID mismatch
Explanation: If the EIGRP neighbor relationship is formed between the two routers, but there is still a connection issue, there may be a routing problem, incorrectly configured passive interfaces, or an access list that is blocking advertisements of remote networks.
