You can include OSPF, static, or directly connected routes in the BGP process with the redistribute command. • Include directly connected or user-configured (static) routes in ROUTER-BGP-AF mode. redistribute {connected | static} • Include specific OSPF routes in IS-IS in ROUTER-BGP-AF mode (1 to 65535). redistribute ospf process-id Disable redistributed routes OS10(conf-router-bgp-af)# no redistribute ospf route-map ospf-to-bgp Enable redistributed routes OS10(conf-router-bgp-af)# redistribute ospf Additional paths The add-path command is disabled by default. 1 Assign an AS number in CONFIGURATION mode. router bgp as-number 2 Enter a neighbor and IP address (A.B.C.D) in ROUTER-BGP mode. neighbor ip-address 3 Enter Address Family mode in ROUTER-NEIGHBOR mode. address-family {[ipv4 | ipv6] [unicast]) 4 Allow the specified neighbor to send or receive multiple path advertisements in ROUTER-BGP mode. The count parameter controls the number of paths that are advertised - not the number of paths received. add-path [both | received | send] count Enable additional paths OS10(config)# router bgp 102 OS10(conf-router-bgp-102)# neighbor 32.1.1.2 OS10(conf-router-neighbor)# address-family ipv4 unicast OS10(conf-router-bgp-neighbor-af)# add-path both 3 MED attributes OS10 uses the MULTI_EXIT_DISC or MED attribute when comparing EBGP paths from the same AS. MED comparison is not performed in paths from neighbors with different AS numbers. 1 Enable MED comparison in the paths from neighbors with different AS in ROUTER-BGP mode. always-compare-med 452 Layer 3
