Hi All,
I'm stumped with an IS-IS route summarization problem and needed some help.
Here's the physical connectivity:
area1 isis area2 rip
----------r3------------r4------------r5--
isis vlsm e0 s1
I want to summarize the different isis area 1 subnets and inject them into
RIP. I've tried using "summary-address a.b.c.d w.x.y.z" under router isis
in R4. But the summary route does not show up in r4's route table and no
routes are injected into RIP's domain when I try to redistribute between the
two routing protocols. What seems to be the problem??
Config for R4:
router isis
summary-address 152.1.1.0 255.255.255.0 level-1-2
redistribute rip metric 1 metric-type internal level-2
net 00.0002.0000.0000.0040.00
!
router rip
redistribute isis level-1-2 metric 2
passive-interface BRI0
passive-interface Ethernet0
network 152.1.0.0
default-metric 2
Route table:
r4# sh ip ro
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, * - candidate
default
U - per-user static route, o - ODR
Gateway of last resort is not set
152.1.0.0/16 is variably subnetted, 8 subnets, 5 masks
i L2 152.1.1.128/25 [115/30] via 152.1.1.65, Ethernet0
i L2 152.1.1.8/30 [115/20] via 152.1.1.65, Ethernet0
i L2 152.1.1.1/32 [115/20] via 152.1.1.65, Ethernet0
i L2 152.1.1.2/32 [115/30] via 152.1.1.65, Ethernet0
C 152.1.2.0/24 is directly connected, Serial1
i L2 152.1.1.4/30 [115/20] via 152.1.1.65, Ethernet0
R 152.1.4.0/24 [120/1] via 152.1.2.2, 00:00:04, Serial1
C 152.1.1.64/26 is directly connected, Ethernet0
