Configuring BGP for Proximity Calculations Configuring the Routing Protocols Used for Network Proximity DETAILED STEPS Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 Command or Action router ospf process-id Example: switch(config)# router ospf 123 Purpose Configures an OSPF routing process and enters routing configuration mode. • process-id-Internally-used, locally-assigned identifier for an OSPF routing process. It can be any positive integer. network ip-address wildcard-mask area area-id Defines the interfaces on which OSPF runs and the area identifier for those interfaces. Example: switch(config-router)# network 26.0.0.0 255.0.0.0 area 1 • ip-address-IP address of the area to be associated with OSPF. • wildcard-mask-Wildcard mask for the IP address to define a range of IP addresses. • area-id-Area that is to be associated with the OSPF address range. area area-id {stub | nssa} Configures an OSPF area as being a stub area or a not-so-stubby area. Example: switch(config-router)# area 1 stub area area-id authentication {message-digest | cleartext} Example: switch(config-router)# area 0 authentication message-digest Enables authentication for an OSPF area. • area-id-Identifier of the area for which authentication is being enabled. This should be a decimal value. • message-digest-Enables message digest 5 (MD5) authentication on the area. • cleartext-Enables clear text authentication on the area. log-adjacency-changes Example: switch(config-router)# log-adjacency-changes router-id ip-address Configures the router to send a syslog message when an OSPF neighbor goes up or down. Specifies that a fixed router ID is to be used. Example: switch(config-router)# router-id 26.0.0.2 • ip-address-Router identifier in IP address format. Configuring BGP for Proximity Calculations Use this task to configure the Border Gateway Protocol (BGP) routing process for proximity calculations performed by the proximity engine.
