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
