ESR series service routers.ESR-Series. User manual
Step Description Command Keys
28 Set IP/IPv6 router address that will be 
used as source IP/IPv6 address in 
transmitted BGP route information 
updates (optional).
esr(config-bgp-neighbor)# update-
source { <ADDR> | <IPV6-ADDR> }
<ADDR> – source IP address, 
defined as AAA.BBB.CCC.DDD 
where each part takes values of 
[0..255];
<IPV6-ADDR> – source IPv6 
address, defined as X:X:X:X::X 
where each part takes values in 
hexadecimal format [0..FFFF].
<IF> – interface specified in 
form given in theTypes and 
naming procedure of router 
interfaces section of CLI 
command reference guide.
<TUN> – tunnel name specified 
in form given in the Types and 
naming procedure of router 
tunnels section.
29 Enable the mode in which the reception 
of routes in the BGP attribute, AS Path 
of which includes the numbers of 
process stand alone system, is allowed 
(optional).
esr(config-bgp-neighbor)# allow-
local-as <NUMBER>
<NUMBER> – threshold 
amount of instances of 
autonomous system number in 
the AS Path attribute at which 
the route will be accepted, the 
range of acceptable values 
[1..10].
30 Enable the BFD protocol on the 
configured BGP neighbor (optional, 
used in conjunction with the update-
source parameter).
esr(config-bgp-neighbor)# bfd-
enable
31 Specify neighbor authentication 
algorithm (optional).
esr(config-bgp-neighbor)# 
authentication algorithm 
<ALGORITHM>
<ALGORITHM> – encryption 
algorithm:
md5 – password is encrypted 
by md5 algorithm.
32 Set the password for neighbor 
authentication (optional).
esr(config-bgp-neighbor)# 
authentication key ascii-text 
{ <CLEAR-TEXT> | encrypted 
<ENCRYPTED-TEXT> }
<CLEAR-TEXT> – password, set 
by the string of 8 to 16 
characters;
<ENCRYPTED-TEXT> – 
encrypted password of 8 to 16 
bytes (from 16 to 32 
characters) in hexadecimal 
format (0xYYYY ...) or 
(YYYY ...).
33 Make neighborhood active. esr(config-bgp-neighbor)#enable
