Hi All,
As am getting closer to the lab - am getting more confused I think. Need
your help with these doubts pls.....
Thanks,
RR.
Redistribution Question--1
IS THIS POSSIBLE?:
---------------------------
scenario: ospf backbone - asbr with area0 and 1 with igrp.
task : do mutual redistribution and send a def.router to igrp only rtr.
Assumptions - the regular ones .........no static routes...etc.,
... AND--you dont have a (non-ospf) classful subnet - on your network.
1.You have to send default route into igrp from an ASBR to a
remote router only running IGRP.
2.Redistributing router is having area 0 and area x and igrp.
I tried using the following on the asbr:
acl 1 permit 0.0.0.0 -- and then a
distribute list out 1 serial 0 -- connecting the remote igrp rtr.
I didnt see the default route on the igrp router.
CAN SOMEONE CONFIRM THAT THIS WILL / WILL NOT WORK FOR IGRP? PLS
my reasoning:
-------------
igrp - so no default-info originate;
choice of ip default network - is not there since there is no classful
subnets (non-ospf) anywhere in the scenario
Redistribution Question--2:
---------------------------
Same scenario - if you are given a non-ospf classful network and
do a 'ip default network a.b.c.0' - i got the default route as
i wanted. But I had a distribute-list to filter the igrp learnt
routes to be permited to go to ospf. And THIS stopped the
154.14.0.0 - E2 routes from appearing in the ospf routers...??WHY?
!
router ospf 1
redistribute connected metric 1 subnets route-map looponly
redistribute igrp 1 metric 150 subnets
passive-interface Serial0
network 145.2.28.0 0.0.3.255 area 0
network 145.2.32.0 0.0.0.3 area 5
distribute-list 34 out igrp 1<---got out of this by removing this.
!
router igrp 1
redistribute ospf 1
passive-interface BRI0
passive-interface Ethernet0
passive-interface Loopback0
network 145.2.0.0
default-metric 8000 100 255 1 1500
distance 120
!
ip classless
ip default-network a.b.c.0
access-list 10 permit 145.2.3.0 0.0.0.255
access-list 10 permit 145.2.192.0 0.0.0.255
access-list 34 permit 145.2.4.0 0.0.0.255
access-list 34 permit 154.14.0.0 0.0.0.255
Pls correct if am wrong in this:
classful-Class B -igrp - with vlsm subnets inside their domain -
when connected through /24 ip add to a classless - ospf - is sending
only /16 of the Class B network through IGRP adhering to its nature.
When this /16 needs to be sent back to rest of network - as long as
we dont have overlaps of the same network AND we have specific routes
to other /24 /xx of the same Class B network - we should not have
reachability problems - provided our configs are fine!
Your feedback is appreciated.
Thanks,
RR.
