Hi fellas,
Can anyone tell me please, Why am I seeing the subnet 150.100.35.0/24 at
the R2 routing table even though I have configured the (
passive-interface default) on the R1 routing table.
Therefore, I should not see the subnet 150.100.35.0 on my routing table of
R2 unless I DO ( no passive-interface f0/1.
below are my configuration:
R1
router rip
version 2
passive-interface default
no passive-interface FastEthernet0/1
network 150.100.0.0
neighbor 150.100.36.2
no auto-summary
output
R1(config-router)#do sir
Codes: C - connected, S - static, 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
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
Gateway of last resort is not set
150.100.0.0/24 is subnetted, 2 subnets
C 150.100.35.0 is directly connected, FastEthernet0/0
C 150.100.36.0 is directly connected, FastEthernet0/1
R2
router rip
version 2
passive-interface default
no passive-interface FastEthernet0/1
network 150.100.0.0
neighbor 150.100.36.1
no auto-summary
alias exec siib show ip int brief
R2(config-router)#
output
150.100.0.0/24 is subnetted, 2 subnets
R 150.100.35.0 [120/1] via 150.100.36.1, 00:00:10,
FastEthernet0/1 --------- . I am not suppose to see this subnet
on my routing table due to (passive-interface default f0/0 on R1)
C 150.100.36.0 is directly connected,
FastEthernet0/1 regardless the
nature of rip protocol that treats its subnets as classfull network range.
R2(config-router)#
thanks,
