multihop
Syntax multihop ttl-value

Description
This command configures the time to live (TTL) value entered in the IP header of packets sent to an
EBGP peer multiple hops away.
This parameter is meaningful only when configuring EBGP peers. It is ignored if set for an IBGP
peer.
The no form of the command is used to convey to the BGP instance that the EBGP peers are directly
connected.
The no form of the command reverts to default values.
Default
1 — EBGP peers are directly connected.
64 — IBGP
Parameters
ttl-value — The TTL value, expressed as a decimal integer.
multipath
Syntax multipath max-paths [eibgp]
no multipath
Context config>service>vprn>bgp
Description This command enables BGP multipath.
When multipath is enabled BGP load shares traffic across multiple links. Multipath can be configured
to load share traffic across a maximum of 16 routes. If the equal cost routes available are more than
the configured value, then routes with the lowest next-hop IP address value are chosen.
This configuration parameter can be set at three levels: global level (applies to all peers), group level
(applies to all peers in group) or neighbor level (only applies to specified peer). The most specific
value is used.
Multipath is effectively disabled if the value is set to one. When multipath is disabled, and multiple
equal cost routes are available, the route with the lowest next-hop IP address will be used.
The no form of the command used at the global level reverts to default values.
Default no multipath — Multipath disabled.
Parameters
integer — The number of equal cost routes to use for multipath routing. If more equal cost routes

exist than the configured value, routes with the lowest next-hop value are chosen. Setting this
value to 1 disables multipath.
