Using One Name Resolver for Multiple Virtual Routers

You can use one name resolver for multiple virtual routers if those virtual routers use the same name servers and belong to the same local domain. To do so, complete the following steps:

1. Configure a name resolver for the first virtual router.
2. Access the context for the second virtual router.
3. Specify that the second virtual router should use the name resolver you configured for the first virtual router.
4. Repeat Steps 2 and 3 for other virtual routers that you want to point to this name resolver.

Example

To configure the virtual router boston to use the same name servers as the default router, enter the following commands.

ip domain-lookup

• Use to configure a virtual router to use the name servers you configured for another virtual router.
• Example

  host1:boston(config)#ip domain-lookup transit-virtual-router default

• Use the no version to stop a virtual router from using the same name servers you configured for another virtual router.
• See ip domain-lookup.
