BGP 5Common diagnostic scenarios• It takes a few minutes for BFD to come up after a partner link comes up over Layer 2.This is an expected behavior. The Brocade device waits for 90 seconds after a port statechanges from down to up before sending the BFD packet out.• When configuring BFD, one end detects a session but the other end does not.The ip ospf bfd command must be enabled at the interface level or the bfd all-interfacescommand must be enabled at the router OSPF level.BGPBorder Gateway Protocol version 4 (BGP4) is the standard Exterior Gateway Protocol (EGP) used onthe Internet to route traffic between Autonomous Systems. BGP maintains a routing table (separatefrom the main router routing table) of the accessible routes and addresses of Autonomous Systemneighbors.BGP show commandsThis section describes the show commands that display BGP information.show debugSyntax: show debugThis command can be used at any time to display debug settings for a device. The followingexample shows debug settings for a device that has only BGP debug settings enabled.Brocade# show debugDebug message destination: consoleIP RoutingBGP:bgp debugging is onBGP:events debugging is onBGP:keepalives debugging is onBGP(RED):bgp debugging is onBGP(RED):events debugging is onBGP(RED):keepalives debugging is onshow ip bgp debugSyntax: show ip bgp debug [memory | network | nexthop | profiling | reset-profiling | route-table |variables |out-policy]This command displays information about BGP network configurations, including next hops,available memory, profile data, and internal variables.• memory - Displays BGP memory pool information.• network - Displays information about BGP networks.• nexthop - Displays BGP next-hop configurations.• profiling - Collects profile data on BGP functions.• reset-profiling - Resets the profile data collection setting.• route-table - Displays routing table information.Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide 11353-1002426-02
