I know I said earlier this doesn't work, but I was doing some other testing
in the lab today, and we use IS-IS as our IGP, so I decided to play with
this for fun.....
IOS is 12.0(23)S1, on a 12016, the neighbor is a Cat6k-MSFC2 running
12.1(8a)E5, adjacency is across SRP, so YMMV....
router isis advanced
redistribute connected route-map ISIS_Deny_Redist
net 49.2901.1720.3124.0065.00
metric-style wide
no hello padding
!
route-map ISIS_Deny_Redist deny 10
match ip address ISIS-test
!
route-map ISIS_Deny_Redist permit 20
!
ip access-list standard ISIS-test
permit 172.30.150.0
The routes we're redistributing....
CR1ADVMO#sh ip ro connected
66.0.0.0/8 is variably subnetted, 13 subnets, 4 masks
C 66.189.240.16/28 is directly connected, GigabitEthernet9/0
C 66.189.240.32/28 is directly connected, SRP1/0
C 66.189.240.128/28 is directly connected, FastEthernet2/4
C 66.189.240.252/30 is directly connected, FastEthernet2/0
172.31.0.0/32 is subnetted, 10 subnets
C 172.31.240.65 is directly connected, Loopback0
172.30.0.0/16 is variably subnetted, 18 subnets, 6 masks
C 172.30.150.0/30 is directly connected, POS7/2
C 172.30.159.252/30 is directly connected, POS6/0
Let's go find a neighbor.....
CR1ADVMO#sh clns is-neighbors
System Id Interface State Type Priority Circuit Id Format
TS1ADVMO SR1/0 Up L1L2 64/64 TSK1ADVMO.02 Phase V
SWC1ADVMO Fa2/4 Up L1L2 64/64 SWC1ADVMO.04 Phase V
SWC1ADVMO Gi9/0 Up L1L2 64/64 SWC1ADVMO.03 Phase V
ER1ADVMO Fa2/0 Up L1L2 64/64 ER1ADVMO.01 Phase V
TSK1ADVMO SR1/0 Up L1L2 64/64 TSK1ADVMO.02 Phase V
And the neighbors routes?
SWC1ADVMO#sh ip ro 172.30.150.0
% Subnet not in table
SWC1ADVMO#sh ip ro 172.31.240.65
Routing entry for 172.31.240.65/32
Known via "isis", distance 115, metric 20, type level-1
Redistributing via isis
Last update from x.x.x.x on Vlan4, 01:06:02 ago
Routing Descriptor Blocks:
* x.x.x.x, from 172.31.240.65, via Vlan5
Route metric is 20, traffic share count is 1
x.x.x.x, from 172.31.240.65, via Vlan4
Route metric is 20, traffic share count is 1
So, it looks like it works after all. If I have time later in the week
I'll try and mock it up on some of the smaller gear...
HTH, sorry for the misinformation earlier...
