Stub Routing Example
A router that is configured as a stub with the eigrp stub command shares connected and summary
routing information with all neighbor routers by default. Four optional keywords can be used with the
eigrp stub command to modify this behavior:
receive-only
connected
static
summary
This section provides configuration examples for all forms of the eigrp stub command. The eigrp stub
command can be modified with several options, and these options can be used in any combination except
for the receive-only keyword. The receive-only keyword will restrict the router from sharing any of its
routes with any other router in that EIGRP autonomous system, and the receive-only keyword will not
permit any other option to be specified because it prevents any type of route from being sent. The three
other optional keywords (connected, static, and summary) can be used in any combination but cannot
be used with the receive-only keyword. If any of these three keywords is used individually with the
eigrp stub command, connected and summary routes will not be sent automatically.
The connected keyword will permit the EIGRP Stub Routing feature to send connected routes. If the
connected routes are not covered by a network statement, it may be necessary to redistribute connected
routes with the redistribute connected command under the EIGRP process. This option is enabled by
default.
The static keyword will permit the EIGRP Stub Routing feature to send static routes. Without this
option, EIGRP will not send any static routes, including internal static routes that normally would be
automatically redistributed. It will still be necessary to redistribute static routes with the redistribute
static command.
The summary keyword will permit the EIGRP Stub Routing feature to send summary routes. Summary
routes can be created manually with the summary address command or automatically at a major
network border router with the auto-summary command enabled. This option is enabled by default.
In the following example, the eigrp stub command is used to configure the router as a stub that
advertises connected and summary routes:
router eigrp 1
network 10.0.0.0
eigrp stub
In the following example, the eigrp stub connected static command is used to configure the router as
a stub that advertises connected and static routes (sending summary routes will not be permitted):
router eigrp 1
network 10.0.0.0
eigrp stub connected static
In the following example, the eigrp stub receive-only command is used to configure the router as a stub,
and connected, summary, or static routes will not be sent:
router eigrp 1
network 10.0.0.0 eigrp
stub receive-only
