Basic configuration tasks
• If you remove a parameter from a peer group, the value for that parameter is reset to the
default for all the neighbors within the peer group, unless you have explicitly set that parameter
on individual neighbors. In this case, the value you set on the individual neighbors applies to
those neighbors, while the default value applies to neighbors for which you have not explicitly
set the value.
NOTE
If you enter a command to remove the remote AS parameter from a peer group, the software
checks to ensure that the peer group does not contain any neighbors. If the peer group does
contain neighbors, the software does not allow you to remove the remote AS. The software
prevents removing the remote AS in this case so that the neighbors in the peer group that are
using the remote AS do not lose connectivity to the Layer 3 Switch.
• Once you add a neighbor to a peer group, you cannot configure the following outbound
parameters (the parameters governing outbound traffic) for the neighbor:
• Default-information-originate
• Next-hop-self
• Outbound route map
• Outbound filter list
• Outbound distribute list
• Outbound prefix list
• Remote AS, if configured for the peer group
• Remove private AS
• Route reflector client
• Send community
• Timers
• Update source
If you want to change an outbound parameter for an individual neighbor, you must first remove
the neighbor from the peer group. In this case, you cannot re-add the neighbor to the same
peer group, but you can add the neighbor to a different peer group. All the neighbors within a
peer group must have the same values for the outbound parameters. To change an outbound
parameter to the same value for all neighbors within a peer group, you can change the
parameter on a peer-group basis. In this case, you do not need to remove the neighbors and
change the parameter individually for each neighbor.
• If you add an outbound parameter to a peer group, that parameter is automatically applied to
all neighbors within the peer group.
• When you add a neighbor to a peer group, the software removes any outbound parameters for
that neighbor from the running configuration (running-config). As a result, when you save the
configuration to the startup-config file, the file does not contain any outbound parameters for
the individual neighbors you have placed in a peer group. The only outbound parameters the
startup-config file contains for neighbors within a peer group are the parameters associated
with the peer group itself. However, the running-config and the startup-config file can contain
individual parameters listed in the previous section as well as the settings for those
parameters within a peer group.
You can override neighbor parameters that do not affect outbound policy on an individual neighbor
basis.
