notes: EIGRP Convergence Timers

- Never change the timers unless asked to.
- Hellos are sent using unicast every 60 sec, on access links with speeds of T1 or slower.
- Hellos are sent using multicast every 5 sec, on all other network links.
- The hold-time interval is 180 sec, on low-speed NBMA networks.
- The hold-time interval is 15 sec, on all other networks.

commands:

- Shows each neighbor in the neighbor table with each timer

show ip eigrp neighbors

- Changes the default hello interval

ip hello-interval eigrp {ASN} {seconds}

note: hello interval @ T1 = 5 seconds, >T1 = 60 seconds.


- Changes the default hold-time

ip hold-time eigrp {ASN} {seconds}
