• 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 Redistribute routes - Example OS10(config)# router bgp 102 OS10(config-router-bgp-102)# address-family ipv4 unicast OS10(configure-router-bgpv4-af)# redistribute ospf 12 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 2. Change the best path MED selection in ROUTER-BGP mode. bestpath med {confed | missing-as-best} • confed-Selects the best path MED comparison of paths learned from BGP confederations. • missing-as-best-Treats a path missing an MED as the most preferred one. • missing-as-worst-Treats a path missing an MED as the least preferred one. 574 Layer 3
