REDISTRIBUTING BGP TO OSPF AND VICE VERSA
Posted on 2013-10-30
We have two 7200 Internet routers connected to the internet running BGP. We have two 3750, one connected to each 7200 router. Currently we are using HSRP but would like to implement OSPF in the DMZ to allow redundancy. We elected to not use GLBP...
We planned to redistribute BGP into OSPF, and OSPF into BGP. However, we are aware the internet routing table can be as large as 25 megabytes in size... way too large for the 128 meg of the 3750 layer 3 switches. Can you provide a sample configuration and explanation of how we can prevent the BGP routes from over subscribing the 3750. I thin we need to use DEFAULT-INFO ORIGINATE command within the OSPF routing protocol route process. Please provide guidance. Much thanks... Chas
