Trying to capture IPv6 BGP hello traffic with monitor capture feature without success.
With the monitor capture for IPv6 traffic active and running; If I traceroute (IPv6) from this same router I do see the IPv6 traceroute traffic but NEVER IPv6 BGP hellos.
NOTE:
IPv6 traceroute traffic is not shown in the below output because I already cleared the V6BUFF buffer before running the show command.
My setup:
monitor capture buffer V6BUFF size 512 max-size 128 linear
monitor capture point ipv6 cef V6PT mfr0.1 both
monitor capture point associate V6PT V6BUFF
monitor capture point start V6PT
Troubleshooting
After disassociating monitor capture point V4PT here are the results:
1941-WAN3#sh mon cap buff all par
Capture buffer V6BUFF (linear buffer)
Buffer Size : 524288 bytes, Max Element Size : 128 bytes, Packets : 0

Associated Capture Points:
Name : V6PT, Status : Active
Configuration:

monitor capture point associate V6PT V6BUFF

Associated Capture Points:

Configuration:

monitor capture point associate V4PT V4BUFF
