where:
peer-group
Is a group ID, which can be a number or a character string.
type
Specifies the type of BGP group you are adding. You can specify one of the
following:
external
In the classic external BGP group, full policy checking is applied to all
incoming and outgoing advertisements. The external neighbors must
be directly reachable through one of the machine's local interfaces.
routing
An internal group which uses the routes of an interior protocol to
resolve forwarding addresses. Type Routing groups will determine the
immediate next hops for routes by using the next hop received with a
route from a peer as a forwarding address, and using this to look up an
immediate next hop in an IGP’s routes. Such groups support distant
peers, but need to be informed of the IGP whose routes they are using
to determine immediate next hops. This implementation comes closest
to the IBGP implementation of other router vendors.
internal
An internal group operating where there is no IP-level IGP, for example
an SMDS network. Type Internal groups expect all peers to be directly
attached to a shared subnet so that, like external peers, the next hops
received in BGP advertisements may be used directly for forwarding.
All Internal group peers should be L2 adjacent.
autonomous-system
Specifies the autonomous system of the peer group. Specify a number from 1 –
65534.
proto
Specifies the interior protocol to be used to resolve BGP next hops. Specify one of
the following:
any
Use any igp to resolve BGP next hops.
rip
Use RIP to resolve BGP next hops.
ospf
Use OSPF to resolve BGP next hops.
static
Use static to resolve BGP next hops.
interface
Interfaces whose routes are carried via the IGP for which third-party next hops
may be used instead. Use only for type Routing group. Specify the interface or all
for all interfaces.
