Enable the comparison of MED 
for routes from each AS 

Optional 

Disabled by default 

Enable the comparison of MED 
for routes from confederation 
peers 

Optional 

Disabled by default 

 

Follow these steps to configure the AS_PATH attribute: 

Enter system view 

— 

Enter BGP view 

bgp as-number 

— 

Enter IPv6 address family view 

— 

Allow the local AS number to 
appear in AS_PATH of routes 
from a peer/peer group and 
specify the repeat times 

peer { ipv6-group-name | 
ipv6-address } allow-as-loop 
[ number ] 

Optional 

Not allowed by default 

Specify a fake AS number for 
an IPv6 peer/peer group 

peer { ipv6-group-name | 
ipv6-address } fake-as 
as-number 

Optional 

Not specified by default. 

Disable IPv6 MBGP from 
considering the AS_PATH 
during best route selection 

Optional 

Enabled by default. 

Configure to carry only the 
public AS number in updates 
sent to a peer/peer group 

peer { ipv6-group-name | 
ipv6-address } public-as-only 

Optional 

By default, IPv6 BGP updates 
carry private AS number. 

Substitute the local AS number 
for the AS number of an IPv6 
peer/peer group identified in 
the AS_PATH attribute 

peer { ipv6-group-name | 
ipv6-address } substitute-as 

Optional 

Not substituted by default 

 

This section describes configurations of IPv6 BGP timers, IPv6 BGP connection soft reset and the 

maximum number of load balanced routes.

IPv6 BGP timers 

After establishing an IPv6 BGP connection, two routers send keepalive messages periodically to each 

other to keep the connection. If a router receives no keepalive message from the peer after the holdtime 

elapses, it tears down the connection. 

When establishing an IPv6 BGP connection, the two parties compare their holdtimes, taking the shorter 

one as the common holdtime. If the holdtime is 0, neither keepalive massage is sent, nor holdtime is 

checked.
