DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide Parameters Default Command Mode Command Default Level Usage Guideline None. None. Router Configuration. Level: 8. (EI Mode Only Command) This command is used to enable the automatic establish BGP peer connection and exchange of IPv4 unicast address family prefixes. If the no bgp default ipv4unicast command is executed, the neighbor activate address family configuration command must be executed in each IPv4 address family session before prefix exchange will occur. The no bgp default ipv4-unicast command is often executed in PE routers when exchanging VPN IPv4 routes. You can verify your settings by entering the show ip bgp parameters command. Example This example shows how to disable the default IPv4 unicast address family for BGP peer session establishment. DXS-3600-32S#configure terminal DXS-3600-32S(config)# router bgp 10 DXS-3600-32S(config-router)# no bgp default ipv4-unicast DXS-3600-32S(config-router)# exit DXS-3600-32S(config)# 7-18 bgp default local-preference This command is used to change the default local preference value. To return the local preference value to the default setting. bgp default local-preference NUMBER no bgp default local-preference Parameters NUMBER Specifies the range of the local reference. This value must be between 0 and 4294967295. Default Command Mode Command Default Level Usage Guideline By default, this option is disabled. BGP sets the default local preference value to100. Router Configuration Mode. Level: 8. (EI Mode Only Command) The local preference attribute is a discretionary attribute that is used to apply the degree of preference to a route during the BGP best path selection process. This attribute is exchanged only between iBGP peers and is used to determine the local policy. The route with the highest local preference is preferred. You can verify your settings by entering the show ip bgp parameters command. Example This example shows how to configure the default value of the local preference to 200 for the autonomous system 65534. DXS-3600-32S#configure terminal DXS-3600-32S(config)#router bgp 65534 DXS-3600-32S(config-router)#bgp default local-preference 200 DXS-3600-32S(config-router)# 76
