OS10(config-router-bgp-10)# template zanzibar OS10(config-router-template)# weight 200 Enable multipath You can have one path to a destination by default, and enable multipath to allow up to 64 parallel paths to a destination. The show ip bgp network command includes multipath information for that network. • Enable multiple parallel paths in ROUTER-BGP mode. maximum-paths {ebgp | ibgp} number Enable multipath OS10(config)# router bgp 10 OS10(conf-router-bgp-10)# maximum-paths ebgp 10 Route-map filters Filtering routes allows you to implement BGP policies. Use route-maps to control which routes the BGP neighbor or peer group accepts and advertises. 1 Enter the neighbor IP address to filter routes in ROUTER-BGP mode. neighbor ipv4-address 2 Enter Address Family mode in ROUTER-NEIGHBOR mode. address-family {[ipv4 | ipv6] [unicast]} 3 Create a route-map and assign a filtering criteria in ROUTER-BGP-NEIGHBOR-AF mode, then return to CONFIG-ROUTER-BGP mode. route-map map-name {in | out} exit • in-Enter a filter for incoming routing updates. • out-Enter a filter for outgoing routing updates. 4 Enter a peer template name in ROUTER-BGP mode. template template-name 5 Enter Address Family mode. address-family {[ipv4 | ipv6] [unicast]} 6 Create a route-map, and assign a filtering criteria in ROUTER-BGP-TEMPLATE-AF mode. route-map map-name {in | out} Filter BGP route OS10(config)# router bgp 102 OS10(conf-router-bgp-102)# neighbor 40.1.1.2 OS10(conf-router-neighbor)# address-family ipv4 unicast OS10(conf-router-bgp-neighbor-af)# route-map metro in OS10(conf-router-bgp-neighbor-af)# exit OS10(conf-router-bgp-102)# template ebgp OS10(conf-router-template)# address-family ipv4 unicast OS10(conf-router-bgp-template-af)# route-map metro in Route reflector clusters BGP route reflectors are intended for ASs with a large mesh. They reduce the amount of BGP control traffic. With route reflection configured properly, IBGP routers are not fully meshed within a cluster but all receive routing information. Layer 3 293
