c880 ISR interfaces and routes not active

[nmdc.kzstan]

Hi,

There is a strange problem with :c880data-universalk9-mz.150-1.M4.bin IOS. I can't ping gateway IP address and

"sh ip route" does not show any routes.

interface FastEthernet4

ip address a.b.82.66 255.255.255.0

duplex auto

speed auto

ip route 0.0.0.0 0.0.0.0 a.b.82.65

yourname#sh ip route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route, + - replicated route

Hi Guys,

   Just add a "ip routing" command on it. If it still does not work, please post your current configuration,excluding sensitive information.

   But you should ping a.b.82.65 without any problem if ISP allows you to do.

HTH,

Toshi

Hi Toshi,

Computer pings gateway without problem with the same network configuration. Sth wrong with 880 isr.

"ip routing" doesn't appear in config after executing, maybe because it is a default.

Hi,

   Okay. Let me check things first.

1. PCs can ping 10.10.10.1(Gateway). Right?

2. Router can ping a.b.82.65. Right?

3. Do you want PCs to connect to the internet. Right? If so you need NAT configuration there.

    You have to connect Lan interface on the router to bring interface-vlan1 up.

HTH,

Toshi

For the moment I want to be able to ping a.b.82.65 from router CLI. Router can't even ping it's fa4 interface IP adress.

I've configured several routers with 12.4 IOS before and never came across such a problem. Maybe there was a change in 15 IOS

and network features should be activated first?

Interface                  IP-Address      OK? Method Status                Protocol

FastEthernet0              unassigned      YES unset  down                  down

FastEthernet1              unassigned      YES unset  down                  down

FastEthernet2              unassigned      YES unset  down                  down

FastEthernet3              unassigned      YES unset  down                  down

FastEthernet4              a.b.82.66    YES NVRAM  up                    up

Vlan1                      10.10.10.1      YES NVRAM  down                  down

yourname#ping a.b.82.66

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to a.b.82.66, timeout is 2 seconds:

.....

Success rate is 0 percent (0/5)

Hi,

   It's wired.

   Please connect the lan interface and then ping 10.10.10.1 from the router itself.  I just wanna know what's happing with your router. Just try shut/no shut on your Fa4 for testing.

HTH,

Toshi

Hi,

Got it working by deleting IP address, entering "ip routing" and configuring IP address after that.

Thank you Toshi.

[Thotsaphon Lueangwattanaphong]

Hi,

    You tried it yourself  .  Okay I give you 5 as well.

Good Job!

Toshi
