I m using ospf between HO and Branches for two links. branch router are 2811 and HO router 3845. when i enable ospf at branch i get all branch route like HO router and a default route. My requirement is each branch get only HO but no other branch. I have no default route.
I attached show ip route status for a branch router.. Why default route comes and why all branch's route come ?
I have 2 ASBR routers, AGFR01RTR03 and AGFR02RTR03, performing OSPF to OSPF redistribution in both ways for the same ***. They also do summarization for our private addressing scheme. It is all working just fine for that part (neighbors, summarization, redistribution).
AGDC01RTR01 --- AGDC02RTR01 (OSPF 1000 ABRs)

AGFR01RTR03 --- AGFR02RTR03 (OSPF 1000 / 53 ASBRs)
Let's focus on AGDC01RTR01 with a specific entry here (IP subnet is fake) :

I have one Cisco router 3845 and one switch 6509, they have two links connected each other via OSPF, I want to have link 1 as high priority, and link 2 as low priority. When the link 1 is down, it can be kicked in to the link 2. How I can implement this setup.

I have two routers and an ASA, all of which are in area 0, it's a pretty simple config. The two routers are connected to some other devices (also in area 0) that pass of an external route to a particular subnet, let's call it 192.168.4.0. The routers are getting it just fine, but the ASA is not:
Looking through the SPROUTE course material they state on several occasions that an ABR will announce a default route in to a standard NSSA area, same as a stub area, because LSA5 external routes are not allowed.

I am not seeing the desired routes present.What kinds of things can I look at to determine the issue? I think I've viewed the OSPF topology database (I'm not that familiar with Brocade) with the show ip ospf routes command and I'm not seeing the desired routes there either.There is no form of route filtering in place. I'll double check, but I do not believe there is any stub routing going on either.

-router ospf 60
-log-adjacency-changes
-redistribute bgp 65199 metric 1500 metric-type 1 subnets
I want to filter down the routes so only a set of specific routes is redistributed.. we have done this in the past with EIGRP by doing a route-map / prefix-list to manage the routes passed into EIGRP.My question is I can replicate the metric and the metric-type in the route-map by doing the following: [code] Do I need to be concerned witht the "subnets" command in this design? What I understand "Subnets".When redistributing routes into OSPF, only routes that are not subnetted are redistributed if the subnets keyword is not specified. I suspect I need to add it! So my final code should look like this..

I have an MPLS router that connects to the core network.This router distributes (per route maps) routes from OSPF into BGP and from BGP into OSPF.The OSPF Process conencts a 6509 to the 7206 MPLS router. There are some routes in the OSPF process that I have filtered out of the 6509. They do not show up inthe 6509 at all and this is the only way they can be getting into the 7206.Checking the 6509 database, this route is gone, but it stays in the 7206 until I clear the route manually. The result is the route still gets distributed into MPLS. [code]
One thing to note, there are two possible OSPF paths the route gets into OSPF, one of them, the route is filtered with distribute-list on the 6509, which means it is still in the database, so it is still in the 7206 database, and still get distributed into BGP on the 7206, correct?
I had already posted for voice modules for cisco 2811 but not able to find it. But here are a few questions regarding i
1. I am trying to configure a cisco 2811 with FXS ports . I am using an NM-HD-2V with a VIC3-2FXS. I am using the right modules. Also I believe we need PVDM mosules installed in the NM-HD-2V. We have PVDM-12 modules. Will that work or is 2811 compatible only with PVDM2-xx modules.
2. We are also trying to configure a cisco 2811 with PRI port. We plan to use an NM-HD-2V and a VWIC-1MFT-T1/E1. If they are correct and if we need only PVDM2-xx modules.
3. Also we are trying to configure a cisco 3845 with PRI and we plan to use the same as in 2811 that is NM-HD-2V, VWIC-1MFT-T1/E1. And here also we are not sure if we need only PVDM2-xx DSP modules.
I have a 3845 that will not let me ping to the internet from my PC.On interface g0/0 I have a connection to a internet connection (another router), using DHCP to get it's address (it gives g0/0 IP 192.168.0.3).On interface g0/1, I have a connection to my LAN (I assign the interface IP 10.10.1.1).
I can ping the router. The router can ping the internet, do DNS resolution, etc.I have ensured routing is enabled. The only route I have configured is a default static route: 0.0.0.0 0.0.0.0 192.168.0.1.Oddly, if I choose 0.0.0.0 0.0.0.0 g0/0, I cannot ping sites on the internet from the router.
I tried setting up ip nat inside for my LAN and ip nat outside for the WAN/internet uplink, but this did not work.
This was the issue, I missed finishing the NAT setup.I can make the router ping out all day, and have my PCs ping the router, but getting the connection between the two is not working.
We have a 3845 router at one of our remote sites. We want to connect the router to our central office using the two gigabit ports. One link would be the primary and the other would be the secondary (backup).
The router is running EIGRP and the two ports would have different ip addresses. How can we set up the router to use gi0/0 as the primary port and gi0/1 as the secondary (backup) port? The backup port would only be used if there was congestion on the primary port or if the primary port went down. Is there a way to force the router to make the primary link the best route?
Remote Router Sample Config:!
int gi0/0
desc primary link to Central Office
ip addr 10.0.1.84 255.255.255.0

I have a Cisco 2620XM Router, running ver. 12.2 (7r). I have OSPF connected, however the OSPF routes are not populating in the sh ip route display. The neighbor relationship is established. The sh ip ospf database does display the other routers running ospf, however only connected (C) and static (S) routes appear.

Have a 1921 that has 3 eth connections (1 LAN, and 2 WAN) - I have 2 seperate OSPF processes (2 areas) on the WAN Ints - both upstream WAN's are sending defaults back to the 1921, and the 1921 is sending it's LAN range to them.
I have ip ospf cost 150 set on the "failover" WAN connection interface (Both on the 1921 and upstream), but the 1921 is preferring the default route from the "failover"?
The default routes are both being received by the 1921, but it's preferring the "failover" Int with the ip ospf cost 150 configured?
I have a Catalyst switch that is redistributing some static routes into OSPF. These are received on a Nexus 7K and appear in the database however the 7K does not add them to its routing table, one of the routes is ignored and not added. I haven't got a clue why this is happening.
The routes on the Catalyst are as follows with ID of 172.30.255.22:
ip route 172.24.59.0 255.255.255.0 10.56.7.46
ip route 192.168.168.0 255.255.255.0 10.56.7.62
on the 7K the database shows:
172.24.59.0 172.30.255.22 1374 0x80001a44 0x1a48 0
192.168.168.0 172.30.255.22 1374 0x80001a45 0x6c5b 0

I`ve seen quite a lot of posts regarding SSH issues and the above SSH error. However the fix mainly involves upgrading clients but in this instance the client is are Cisco routers 3845 / 2811 - which we use for out and inband management.Connectivity / routing etc is proven. Using SSH v2 the actual 6500 chassis where the ACE is physically located works fine. Configuring SSH v1 on the ACE module allows connections via the 3845/2811`s but we cannot use this.Both have the following IOS Version 12.4(24)T4. I have tried various key sizes on the ACE module.
