LAB 11: EIGRP Stub
Task 1: Configure EIGRP Stub
In the configuration mode of router configure loopbacks with network address in sequence.
R1:
interface loopback 1
ip address 11.0.1.1 255.255.255.0
exit
interface loopback 2
ip address 11.0.2.1 255.255.255.0
exit
interface loopback 3
ip address 11.0.3.1 255.255.255.0
exit
Configure EIGRP stub with connected option
R1:
router eigrp 100
eigrp stub ?
connected Do advertise connected routes
leak-map Allow dynamic prefixes based on the leak-map
receive-only Set receive only neighbor
redistributed Do advertise redistributed routes
static Do advertise static routes
summary Do advertise summary routes
eigrp stub connected
exit
(EIGRP Stub router will do advertise its connected routes to the neighbor router.)
Configure EIGRP stub with connected static option
R1:
router eigrp 100
eigrp stub static
exit
(EIGRP Stub router will do advertise static routes.)
Configure EIGRP stub with receive only option
R1:
router eigrp 100
eigrp stub receive-only
exit
(EIGRP Stub router will only receive routes from its neighbor but will not advertise any routes to its neighbor.)
Task 2: Verification:
Verify route in neighbors router routing table by following command:
R2#show ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override

D 44.0.3.0 [90/2323456] via 23.0.0.3, 01:39:35, Ethernet0/0
(Router R2 will not receive 11 network from Stub router because Stub router will only receive and will not advertise its own 11 network to Router R2.)
Configure no auto summary and verify routes on neighbor router routing table
R1:
router eigrp 100
no auto-summary
exit
