Task1
Configure R1 to send hello towards R3 every 2 seconds on S0/1 interface. THe hold interval should be 3 times the hello timer. Do not change timers on R3.
Task 2
Configure EIGRP so that the routers should respond to EIGRP Query packet within 60 seconds before the neighbor is declared SIA.
Task 3
Configure EIGRP so that the routers will hold known routes for NFS-capable neighbor for 2 minutes during switch-over operation.
Lab Solution
Task1
Configure R1 to send hello towards R3 every 2 seconds on S0/1 interface. THe hold interval should be 3 times the hello timer. Do not change timers on R3.
R1 Configuration:
!
interface Serial0/1
ip address 10.1.13.1 255.255.255.0
ip hello-interval eigrp 1 2
ip hold-time eigrp 1 6
!
ip address 10.1.13.1 255.255.255.0
ip hello-interval eigrp 1 2
ip hold-time eigrp 1 6
!
Note!
In EIGRP the hello and hold interval do not have to match between neighbors (for consistency sake they should be set identically though).
Task 2
Configure EIGRP so that the routers should respond to EIGRP Query packet within 60 seconds before the neighbor is declared SIA.
On All Routers:
!
router eigrp 1
timers active-time 1
!
Task 3
Configure EIGRP so that the routers will hold known routes for NFS-capable neighbor for 2 minutes during switch-over operation.
On All Routers:
!
router eigrp 1
timers nsf route-hold 120
!
Verification:
Pic 2 - NFS Route-Hold Timer.
NFS route-hold timer ranges from 20-300 seconds. The default is 240 sec. and can be displayed using 'show ip protocols' command.
