Cisco Route Tagging Problem

Posted on 2016-10-02

Hello Experts,

We have created a network as shown in the topology.

The goal is for subnets/networks in LAN_SW to tagged and the tagged networks to be recognized by routers, CPE, PE CORE_P, REMOTE_PE, REMOTE_CPE and finally placed in the routing table of REMOTE_LAN_SW.

I have tagged the address 7.7.7.7/32 with tag 100 in LAND_SW. However, as you will see in show commands, the tag isn't being picked by eigrp.

Can you please take a look at the configuration and show commands and let me know where I might be going wrong?

I have attached the configuration and show commands

Kind regards

What 7.7.7.7/32? I don't see that one configured anywhere. :)

Hi Predrag,

I meant prefix list

ip prefix-list TAG seq 5 permit 7.7.7.7/32

Cheers

There is no 7.7.7.7/32, should be received from somewhere to be inserted in routing table and tagged. How can you tag something that is not there?
Maybe I just can't see it... Do you have it anywhere?

In LAN_SW, there is the following prefix list

ip prefix-list TAG seq 5 permit 7.7.7.7/32

That is command for tagging, but you do not have that network present.
So, what are you tagging??

7.7.7.7/32 is not present in the routing table of any device (not configured anywhere and not in routing table of any device).

Simplification:
You need to have paper and pen to sign a paper. Pen it your prefix list.
If you want to sign a paper you need to have paper. Route is paper.
Where is your paper???

OK,

I added the following static route

ip route 7.7.7.7 255.255.255.255 ethernet 0/0

LAN_SW#show ip eigrp topology
EIGRP-IPv4 Topology Table for AS(100)/ID(9.9.9.9)
Codes: P - Passive, A - Active, U - Update, Q - Query, R - Reply,
       r - reply Status, s - sia Status

P 50.50.50.50/32, 0 successors, FD is Inaccessible, tag is 10
        via 192.168.0.2 (307200/51200), Ethernet0/0
P 100.100.100.100/32, 0 successors, FD is Inaccessible, tag is 10

Hi Predrag

I see where I was going wrong.

As you suggested the, the first problem was not having the static route in first place.

The second problem was because I forgot the following command:

redistribute static metric 1000 0 255 1 1500 route-map TAG

router eigrp 100
redistribute connected metric 1000 0 255 1 1500 route-map TAG
redistributing directly connected networks (like loopback - so you can create loopback)
interface loopback1
 ip add 7.7.7.7 255.255.255.255
ip route 7.7.7.7 255.255.255.255 ethernet 0/0
redistribute static - redistribute static route into EIGRP (static routes that are placed in routing table)

So, that should be it. :)
