A. The redistribution of iBGP routes into Interior Gateway Protocol (IGP)—Enhanced Interior Gateway Routing Protocol/Open Shortest Path First/Intermediate System-to-Intermediate System (EIGRP/OSPF/IS-IS)—can cause routing loops within the Autonomous System, which is not recommended. By default, iBGP redistribution into IGP is disabled. Issue the bgp redistribute-internal command in order to enable redistribution of iBGP routes into IGP. Precautions must be taken to redistribute specific routes using route-maps into IGP. A sample configuration for redistributing a iBGP learned default route 0.0.0.0/0 into EIGRP is shown in this output. Configurations for OSPF/IS-IS are similar. router bgp 65345 […] bgp redistribute-internal ! router eigrp 10 […] redistribute bgp 65345 route-map check-def ! ip prefix-list def-route seq 5 permit 0.0.0.0/0 !
