www.dell.com | support.dell.com interface distance permanent tag tag-value Enter the following keywords and slot/port or number information: • For a 1-Gigabit Ethernet interface, enter the keyword GigabitEthernet followed by the slot/port information. • For a loopback interface, enter the keyword loopback followed by a number from zero (0) to 16383. • For the null interface, enter the keyword null followed by zero (0). • For a Port Channel interface, enter the keyword port-channel followed by a number: C-Series and S-Series Range: 1-128 E-Series Range: 1 to 32 for EtherScale, 1 to 255 for TeraScale. • For a SONET interface, enter the keyword sonet followed by the sonet followed by the slot/port information. • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet followed by the slot/port information. • For a VLAN, enter the keyword vlan followed by a number from 1 to 4094. (OPTIONAL) Enter a number as the distance metric assigned to the route. Range: 1 to 255 (OPTIONAL) Enter the keyword permanent to specify the route is not removed, even if the interface assigned to that route goes down. The route must be up initially to install it in the routing table. If you disable the interface with an IP address associated with the keyword permanent, the route disappears from the routing table. (OPTIONAL) Enter the keyword tag followed by a number to assign to the route. Range: 1 to 4294967295 Defaults Not configured. Command Modes CONFIGURATION Command History Version 8.3.5.0 Version 8.2.1.0 Version 8.1.1.0 Version 7.9.1.0 Version 7.6.1.0 Version 7.5.1.0 pre-Version 6.1.1.0 Introduced on the S55. Support 4094 VLANs on E-Series ExaScale (prior limit was 2094) Introduced on E-Series ExaScale Introduced VRF on the E-Series Introduced on S-Series Introduced on C-Series Introduced for E-Series Usage Using the following example of a static route: Information ip route 33.33.33.0 /24 gigabitethernet 0/0 172.31.5.43 • The software installs a next hop that is not on the directly connected subnet but which recursively resolves to a next hop on the interface's configured subnet. In the example, if gig 0/0 has ip address on subnet 2.2.2.0 and if 172.31.5.43 recursively resolves to 2.2.2.0, FTOS installs the static route. • When the interface goes down, FTOS withdraws the route. • When the interface comes up, FTOS re-installs the route. • When recursive resolution is "broken," FTOS withdraws the route. • When recursive resolution is satisfied, FTOS re-installs the route. 530 | IPv4 Routing
