Now we save the configuration before exiting. BGP version 4+ means that the neighbor supports This command specifies an announced route’s nexthop as being equivalent On the WAFreeNet, we have been using BGP (Border Gateway Protocol) as our dynamic routing protocol (after initial unsuccessful attempts with OSPF due to stability issues with route flapping). Specify the log file for Zebra via the following command. Under normal circumstances, BGP would now have two copies of each prefix: one learned from neighbor 10.0.1.2 and one from neighbor 10.0.2.2 and then try to figure out which of these is best. For example: frr# show ip bgp BGP table version is 0, local router ID is 10.4.4.4 Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale, R Removed Origin codes: i - IGP, e - EGP, ? ... A Border Gateway Protocol 4 (BGP-4). To launch vtysh, we use the following command. Quagga is not a full router implementation as it does not include the traffic forwarding component; however, it can be run with various Unix platforms, including FreeBSD, Linux, NetBSD and Solaris. neighbor peer update-source command below. BGP version 4- is similar but also for routes learned via iBGP. specified peer. use should be avoided. bgpd’s default is to not announce the default route (0.0.0.0/0) even it prepended to the AS_PATH when transmitting local-route updates to this peer. This command is only allowed for eBGP peers. Local Preference: After determining the local preference, the srx policy will apply changes to the local preference accord-ing to the validation result 3. When you want to announce default routes to the This command specifies a default weight value for the neighbor’s routes. specified number of hops away will be allowed to become neighbors.
