1. Enable soft-reconfiguration for the BGP neighbor and BGP template in ROUTER-BGP mode. BGP stores all the updates that the neighbor receives but does not reset the peer-session. Using this command starts the storage of updates, which is required for inbound soft reconfiguration. neighbor {ip-address} soft-reconfiguration inbound 2. Enter Address Family mode in ROUTER-NEIGHBOR mode. address-family {[ipv4 | ipv6] [unicast]} 3. Configure soft-configuration for the neighbors belonging to the template. soft-reconfiguration inbound 4. Clear all information or only specific details in EXEC mode. clear ip bgp {neighbor-address | *} [soft in] • * - Clears all peers. • neighbor-address- Clears the neighbor with this IP address.

To redistribute iBGP routes to OSPF, configure a route-map and apply it to the redistribute command under the OSPF configuration. Sample configuration The following sample topology has two switches, Core 1 and Core 2, that are connected to each other and share routes using OSPF. A border router BR is connected to Core 1 and shares routes using internal BGP. Core 1 redistributes the routes that are learned by iBGP to OSPF to Core 2. Configuration on BR BR has BGP configured which forms BGP neighbor adjacency with Core 1. interface Loopback0 ip address 192.168.100.1/24 Layer 3 541
