network short-cut
Use network short-cut to increase the preference for a received EBGP route. This EBGP route is called
shortcut route.
Use undo network short-cut to cancel the configuration.
Syntax
In BGP IPv4 unicast instance view/BGP-VPN IPv4 unicast instance view:
network ip-address [ mask | mask-length ] short-cut
undo network ip-address [ mask | mask-length ] short-cut
In BGP IPv6 unicast instance view/BGP-VPN IPv6 unicast instance view:
network ipv6-address prefix-length short-cut
undo network ipv6-address prefix-length short-cut
Default
A received EBGP route has a preference of 255.

Parameters
ip-address: Specifies an IPv4 network address. If the mask or mask-length is not specified, natural mask
is used.
mask: Specifies a mask of the network address in dotted decimal notation.
mask-length: Specifies a mask length in the range of 0 to 32.
ipv6-address: Specifies an IPv6 network address.
prefix-length: Specifies a prefix length in the range of 0 to 128.
Usage guidelines
Different routing protocols might find different routes to the same destination. However, not all of those
routes are optimal. For route selection, routing protocols, direct routes, and static routes are assigned
different preferences. The route with the highest preference is preferred.
By default, the preference of an EBGP route is lower than a local route. If a device has an EBGP route and
a local route to reach the same destination, the device does not select the EBGP route. You can use the
network shortcut command to configure the EBGP route to have the same preference as the local route
so the EBGP route is more likely to become the optimal route.
