Command Example: show isis databaseControl routing updatesUse the following commands in ROUTER ISIS mode to control the source of IS-IS route information.Distribute RoutesAnother method of controlling routing information is to filter the information through a prefix list. Prefixlists are applied to incoming or outgoing routes and routes must meet the conditions of the prefix lists orFTOS does not install the route in the routing table. The prefix lists are globally applied on all interfacesrunning IS-IS.Command Syntax Command Mode Purposepassive-interface interface ROUTER ISIS Disable a specific interface from sending or receivingIS-IS routing information.Enter the type of interface and slot/port information:• For a 1-Gigabit Ethernet interface, enter the keywordGigabitEthernet followed by the slot/portinformation.• For the Loopback interface on the RPM, enter thekeyword loopback followed by a number from 0 to16383.• For a port channel, enter the keyword port-channelfollowed by a number from 1 to 255 for TeraScaleand ExaScale, 1 to 32 for EtherScale.• For a SONET interface, enter the keyword sonetfollowed by slot/port information.• For a 10-Gigabit Ethernet interface, enter thekeyword TenGigabitEthernet followed by the slot/port information.• For a VLAN, enter the keyword vlan followed by anumber from 1 to 4094.E-Series ExaScale platforms support 4094VLANs with FTOS version 8.2.1.0 and later.Earlier ExaScale supports 2094 VLANS.FTOS#show isis databaseIS-IS Level-1 Link State DatabaseLSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OLB233.00-00 0x00000003 0x07BF 1088 0/0/0eljefe.00-00 * 0x00000009 0xF76A 1126 0/0/0eljefe.01-00 * 0x00000001 0x68DF 1122 0/0/0eljefe.02-00 * 0x00000001 0x2E7F 1113 0/0/0Force10.00-00 0x00000002 0xD1A7 1102 0/0/0IS-IS Level-2 Link State DatabaseLSPID LSP Seq Num LSP Checksum LSP Holdtime ATT/P/OLB233.00-00 0x00000006 0xC38A 1124 0/0/0eljefe.00-00 * 0x0000000D 0x51C6 1129 0/0/0eljefe.01-00 * 0x00000001 0x68DF 1122 0/0/0eljefe.02-00 * 0x00000001 0x2E7F 1113 0/0/0Force10.00-00 0x00000004 0xCDA9 1107 0/0/0FTOS#
