Hey all,
I'm trying to work out what does "passive-interface <Serial0>" do...
RTA -- RTB -- RTC -- RTD - 156.26.32.0/24 & 156.26.33.0/24
Both RTA, B & C are using OSPF.
RTC also uses RIP v2, so it's an ASBR.
And RTD uses RIPv2.
RTC's Serial 0 interface is connecting to RTB &
RTC's Serial 1 interface is connecting to RTD
RTD advertise the 2 networks 156.26.32.0/24 & 156.26.33.0/24 with
RIPv2.
RTC is doing mutual redistribution, where the RIPv2 is being
redistributed into OSPF, and OSPF is being redistributed back into
RIP.
And there is a distribute-list at RTC to stop RTD to advertise any
OSPF learned routes back into OSPF.
router rip
version 2
redistribute ospf 3 metric 5
network 10.0.0.0
distribute-list 1 in Serial1
no auto-summary
!
access-list 1 permit 156.26.32.0 0.0.1.255
But I couldn't find the use of the "passive-interface" command.
RouterC(config)#router rip
RouterC(config-router)#passive-interface serial 0
It just doesn't seems to do anything. With it or without it, my OSPF
routers (RTA & RTB) can get the RIP routes and able to reach
156.26.32.0 & 33.0 network.
Any ideas are welcome.
H.
