Usage
Information
To prevent loops, the
neighbor ebgp-multihop
command does not install
default routes of the multihop peer. Networks not directly connected are not
considered valid for best path selection.
neighbor fall-over
Enable or disable fast fall-over for BGP neighbors.
Syntax
neighbor {
ipv6-address
|
peer-group-name
} fall-over
To disable, use the
no neighbor {
ipv6-address
|
peer-group-name
}
fall-over
command.
Parameters
ipv6-address
Enter the IPv6 address in the x:x:x:x::x format.
NOTE: The :: notation specifies successive hexadecimal
fields of zeros.
peer-group-
name
Enter the name of the peer group.
Defaults
Disabled.

History
Version 9.2(0.0)
Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
When you enable fall-over, BGP keeps track of IP or IPv6 reachability to the peer
remote address and the peer local address. Whenever either address becomes
unreachable (for examle, no active route exists in the routing table for peer IP or
IPv6 destination/local address), BGP brings down the session with the peer.

neighbor filter-list
Configure a BGP filter based on the AS-PATH attribute.
Syntax
neighbor {

|
peer-group-name
} filter-list
as-path-
name
{in | out}
To delete a BGP filter, use the
no neighbor {
