Re: [HELP] help with new router config Cisco 1921said by DocLarge:No question to made. More like a statement. I'm skimming through a document pertaining to your router... EDITOkay, set up a management vlan on your 1921 similar to what you had on your 871: int vlan 1 ip address 10.10.10.1 255.255.255.0 no shut I don't recall it leting me do that. |

Try assigning the ip address to your gi0/1 interface:
int gi0/0 ip address 10.10.10.1 255.255.255.0 no shut speed 100 duplex full |

Give me a couple of seconds while I try this. I mean more like 4 to 5 min so the cable modem will forget the mac address. k |

so it seems now that I can ping my internal network but I still can not route to the outside (a.k.a Ping the internet from a pc) It looks like I am getting closer but something is still missing here. |

Closer is good... I'm taking a look at my config I was running before I switched my 871w over to a static ip to see what's still missing... By the way, do you know the ip addresses of your ISPs DNS servers? If you're not going to use the command I mentioned before (ip dhcp client update dns), it might not hurt using this command: ip name-server [ISP DNS Srvr IP Address Here] It almost is starting to sound like there's an issue in your ip routing table (hmmm) |

yea it looks that way. I usually hard code the DNS servers on my machine. Don't ask me why i do that but it seems to work for me. The one thing I did notice is in the Sh ip Route table.
Look below : new 921 route table
orion1#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
Gateway of last resort is 71.200.56.1 to network 0.0.0.0
S* 0.0.0.0/0 [254/0] via 71.200.56.1 68.0.0.0/32 is subnetted, 1 subnets S 68.87.64.10 [254/0] via 71.200.56.1, GigabitEthernet0/0 71.0.0.0/8 is variably subnetted, 2 subnets, 2 masks C 71.200.56.0/22 is directly connected, GigabitEthernet0/0 L 71.200.57.11/32 is directly connected, GigabitEthernet0/0
old route table: Cisco 871
orion#sh ip route Codes: 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
Gateway of last resort is 71.200.56.1 to network 0.0.0.0
68.0.0.0/32 is subnetted, 1 subnets S 68.87.64.10 [254/0] via 71.200.56.1, FastEthernet4 71.0.0.0/22 is subnetted, 1 subnets C 71.200.56.0 is directly connected, FastEthernet4 S* 0.0.0.0/0 [254/0] via 71.200.56.1
See where 71.0.0.0/8 has two 2 subnets (cisco 1921)
and 71.0.0.0/22 has 1 subnet (Cisco 871)
WHY? |

I don't think I've ever seen that. For some reason, you're gi0/0 interface is finding another device (possibly latent entry from switching between your 871 and 1921??).
Try doing a "clear ip route *" and see if it drops off... |

Try doing a "clear ip route *" from and see if it drops off... I can try but it will take at least 5 to 10 mins to switch over. If you want to stay here I will try it now. |

No prob... I've got access from my I-phone...
EDIT
What I sometimes do in this instance is stick a consumer router on line (i.e, Linksys WRV200, Netgear FVS114), and set it up for DHCP. Then from there, I take a look at it's routing table entries for a comparison.
Oh, I forgot something; when you're back up, do a "sh ip int brief" and see if your gi0/0 is up and running... |

no luck
I have cleared the ip route tables and I always do a sh ip int brief. |
