After you execute the undo peer advertise-ext-community command, BGP, upon receiving a route with
the extended community attribute, removes the extended community attribute before sending the route to
the peer or peer group.
Examples
# In BGP IPv4 unicast address family view, advertise the extended community attribute to peer group
test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv4-family unicast
[Sysname-bgp-ipv4] peer test advertise-ext-community
# In BGP-VPN IPv4 unicast address family view, advertise the extended community attribute to peer
group test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ip vpn-instance vpn1
[Sysname-bgp-vpn1] ipv4-family unicast
[Sysname-bgp-ipv4-vpn1] peer test advertise-ext-community
# In BGP IPv6 unicast address family view, advertise the extended community attribute to peer group
test.
<Sysname> system-view
[Sysname] bgp 100
[Sysname-bgp] ipv6-family unicast
[Sysname-bgp-ipv6] peer test advertise-ext-community

peer allow-as-loop
Use peer allow-as-loop to allow a local AS number to exist in the AS_PATH attribute of routes from a peer
or peer group, and to configure the number of times the local AS number can appear.
Use undo peer allow-as-loop to restore the default.
