7604 & default network

Hello,

We have a 7604 with c7600rsp72043-ipservices-mz.122-33.SRB1

We use the command "ip default-network ...", but the router does not mark it as candidate default. There is no problem with the advertisement of this particular network, as when we redistribute it to another router (7505) which also has the default network command it marks it as candidate default.

What could be the problem?

Thank you in advance

Re: 7604 & default network

HI Maria, [Pls Rate if HELPS]

For every network configured with ip default-network, if a router has a route to that network, that route is flagged as a candidate default route.

For Eg:

Router#show ip route

Codes: C - connected, S - static

Gateway of last resort is not set

S 198.10.1.0/24 [1/0] via 161.44.192.2

Note the static route to 198.10.1.0 via 161.44.192.2 and that the gateway of last resort is not set. If you configure ip default-network 198.10.1.0, the routing table changes to this:

Router#show ip route

Codes: C - connected, S - static, * - candidate default

Gateway of last resort is 161.44.192.2 to network 198.10.1.0

S* 198.10.1.0/24 [1/0] via 161.44.192.2

The gateway of last resort is now set as 161.44.192.2

Hope I am Informative.

Re: 7604 & default network

Well, the route appears in our routing table

Router#show ip route

B 193.0.0.0/21 [20/0] via ....

we enter the following command

ip default-network 193.0.0.0

but the router does not mark it as candidate default.

HI Maria, [Pls Rate if HELPS]

With the output provided, i can understand the 193.0.0.0/21 "BGP" learned route.

Normally, when you BET between routes learned from a Routing Protocol & a Satic Route means the resulting winner will be the Routing Protocol learned routes.

Hope I am Informative.

Pls rate if HELPS

Re: 7604 & default network

My problem is that the route is not marked as candidate default at all

Thank you for your time
