EIGRP issue "Ignore multicast Hello"

Hi,

 The ASA5515 isn't detectng eigrp routes. I have checked and rechecked and can't seem to figure out what the issue is. Below is the output for troubleshooting. Why is it ignoring multicast?


router eigrp 101
 neighbor 10.10.YY.3 interface ENS
 neighbor 10.10.YY.6 interface ENS
 network 10.10.nn.0 255.255.255.0
 network 10.10.YY.0 255.255.255.0
 redistribute connected
 redistribute static

Hey,Its because you have both

Hey,

Its because you have both static and network statement for neighbor 10.10.YY.3 so EIGRP is communicating on unicast and ignoring multicast.

HTH.

Hey Rajeev,  I found out what

Hey Rajeev,

 

 I found out what the issue was.Was reading on router adjacencies  and 

"After a static neighbor is defined, all EIGRP multicasts on the interface through which the neighbor is reachable will be disabled."

 

Removed the nieghbor command and Bingo!

Hi Rajeev,  Its not ignoring

Hi Rajeev,

 

 Its not ignoring packets just from 10.10.YY.3. Its ignoring from all other EIGRP neighbiors (not in RED).

 

10.10.YY.1, 10.10.YY.2, 10.10.YY.3, 10.10.YY.4, 10.10.YY.6

Did you check the physical

Did you check the physical link of G0/1 for any link flaps on ASA or other end. Also check for any duplex and speed issues.

RS.
