API Guide

Redistribute routes
Add routes from other routing instances or protocols to the BGP process. 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
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}
