Below is a routing table from a scenario i am working on. It is for OSPF
over NBMA in Point-to-Point mode over subinterfaces. It is probably an easy
explanation but something i would like to be clear on. My hub location is
the 2521 which is where this table is from. I have three routers connected
to it VIA subinterfaces running through a 2523 acting as the switch. I used
192.168.1.0 /30 for the wan addresses. On my remote 2501 connected VIA
Serial0.102 i added loopback interface 1 ip address 192.168.1.33 /27 as i
wanted to see how the VLSM address showed up in the route table of the 2521.
The table is as follows.
2521#show ip route
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
192.168.1.0/24 is variably subnetted, 4 subnets, 2 masks
O 192.168.1.33/32 [110/1563] via 192.168.1.6, 00:00:17, Serial0.102
C 192.168.1.8/30 is directly connected, Serial0.103
C 192.168.1.12/30 is directly connected, Serial0.104
C 192.168.1.4/30 is directly connected, Serial0.102
2521#
My question is why does the address show up as 192.168.1.33/32 instead of
/27 as i expected. I have dug around through my books and i understand VLSM
but cant find a simple explanation as to why this shows up as a /32 address.
Can anybody explain this to me?
Thanks,
Ed
