CanogaOS Command Reference
16-51
16.76 synchronization
Use this command to enable IGP synchronization of Internal BGP (iBGP) learned routes with the Internal
Gateway Protocol (IGP) system in the router configuration mode or in the address-family configuration mode.
Use the no parameter with this command to disable this function.
Command Syntax
(no) synchronization
Default
IGP synchronization is disabled.
Command Mode
Router mode
Address Family mode
ipv4 unicast
ipv4 multicast
ipv6 unicast
Usage
Synchronization is used when a BGP router should not advertise routes learned from iBGP neighbors, unless
those routes are also present in an IGP (for example, OSPF). Synchronization may be enabled when all the
routers in an autonomous system do not speak BGP, and the autonomous system is a transit for other
autonomous systems. The no synchronization command is used when BGP router can advertise routes
learned from its iBGP neighbors without waiting for the IGP reachability to be present.
Examples
The following example enables IGP synchronization of iBGP routes in Router mode.
Switch# configure terminal
Switch(config)# router bgp 11
Switch(config-router)# synchronization
The following example enables IGP synchronization of iBGP routes in the
IPv6-Unicast address family.
Switch# configure terminal
Switch(config)# router bgp 11
Switch(config)# address-family ipv6 unicast
Switch(config-af)# synchronization
16.77 router bgp
Use this command to configure a BGP routing process.
Use the no parameter with this command to disable a routing process.
