Re: Redistributing OSPF thru E-BGP Problem

crumdub12 · ‎02-22-2007

Have a problem, Have a mesh network,

Device A and Device B connect into Cisco 7609 to route to other devices on the network.

Until recently, they all used E-BGP , and traffic was routed:

Device A => Cisco => Network

Device B => Cisco => Network

Device A and Device B have fibre connection.

This was correct.

We changed Device B from E-BGP to OSPF, and REDISTRIBUTEd on Cisco onto network.

Now Device A routes all traffic thru Device B to Cisco !!!

Device A=> Device B => Cisco => Network

Device B => Cisco => Network

Think there is something wrong with Distributive Metric , but am restricted as Device A and B do not have as expansive command set as Cisco 7600...

Any Ideas ??

Hi,

Can you give previous setup digram and changed setup diaagram and Configuration. Previous and you changed both.

See, as of your talk only we can conclude.... You were using E-BGP (i.e EGP) and Now You are using OSPF (i.e IGP).

It will not performe between AS as BGP.

Any way tell us smothing more about this.

Regards,

Unfortunately, The devices are GUI based, and settings were not changed on Device A, but changed on Device B, E-BGP was switched off , and OSPF was switched on, The OSPF on Cisco is as follows.

Relevant IP addresses are:

Device A => Cisco 192.168.216.93-94/30

Device A => Device B 192.168.216.201-202/30

Device B => Cisco 192.168.216.113-114/30

Hope this helps..
