Static routes, which define explicit paths between two routers, cannot be automatically updated; you must manually reconfigure static routes when network changes occur. Static routes use less bandwidth than dynamic routes. No CPU cycles are used to calculate and analyze routing updates. You can supplement dynamic routes with static routes where appropriate. You can redistribute static routes into dynamic routing algorithms but you cannot redistribute routing information calculated by dynamic routing algorithms into the static routing table. You should use static routes in environments where network traffic is predictable and where the network design is simple. You should not use static routes in large, constantly changing networks because static routes cannot react to network changes. Most networks use dynamic routes to communicate between routers but may have one or two static routes configured for special cases. Static routes are also useful for specifying a gateway of last resort (a default router to which all unroutable packets are sent). This section includes the following topics: •Administrative Distance •Directly Connected Static Routes •Fully Specified Static Routes •Floating Static Routes •Remote Next Hops for Static Routes •Virtualization Support Configuring a Static Route You can configure a static route on the router. SUMMARY STEPS 1. configure terminal 2. ip route {ip-prefix | ip-addr ip-mask} {[next-hop | nh-prefix] | [interface next-hop | nh-prefix]} [tag tag-value [pref]] 3. (Optional) show ip static-route 4. (Optional) copy running-config startup-config DETAILED STEPS Command Purpose Step 1 configure terminal Example: switch# configure terminal switch(config)# Enters configuration mode. Step 2 ip route {ip-prefix | ip-addr ip-mask} {[next-hop | nh-prefix] | [interface next-hop | nh-prefix]} [tag tag-value [pref] Example: switch(config)# ip route 192.0.2.0/8 ethernet 1/2 192.0.2.4 Configures a static route and the interface for this static route. You can optionally configure the next-hop address. The preference value sets the administrative distance. The range is from 1 to 255. The default is 1. Step 3 show ip static-route Example: switch(config)# show ip static-route (Optional) Displays information about static routes. Step 4 copy running-config startup-config Example: switch(config)# copy running-config startup-config (Optional) Saves this configuration change. This example shows how to configure a static route: switch# configure terminal switch(config)# ip route 192.0.2.0/8 192.0.2.10 switch(config)# copy running-config startup-config Use the no ip static-route command to remove the static route. Configuring Virtualization You can configure a static route in a VRF. SUMMARY STEPS 1. configure terminal 2. vrf context vrf-name 3. ip route {ip-prefix | ip-addr ip-mask} {next-hop | nh-prefix | interface} [tag tag-value [pref] 4. (Optional) show ip static-route vrf vrf-name 5. (Optional) copy running-config startup-config DETAILED STEPS Command Purpose Step 1 configure terminal Example: switch# configure terminal switch(config)# Enters configuration mode. Step 2 vrf context vrf-name Example: switch(config)# vrf context StaticVrf Creates a VRF and enters VRF configuration mode. Step 3 ip route {ip-prefix | ip-addr ip-mask} {next-hop | nh-prefix | interface} [tag tag-value [pref] Example: switch(config-vrf)# ip route 192.0.2.0/8 ethernet 1/2 Configures a static route and the interface for this static route. You can optionally configure the next-hop address. The preference value sets the administrative distance. The range is from 1 to 255. The default is 1. Step 4 show ip static-route vrf vrf-name Example: switch(config-vrf)# show ip static-route (Optional) Displays information on static routes. Step 5 copy running-config startup-config Example: switch(config-vrf)# copy running-config startup-config (Optional) Saves this configuration change. This example shows how to configure a static route: switch# configure terminal switch(config)# vrf context StaticVrf switch(config-vrf)# ip route 192.0.2.0/8 192.0.2.10 switch(config-vrf)# copy running-config startup-config
