User Manual / IBR1100/IBR1150
• Multipath Relax: Select "relax" to allow multi-path routing to different ASNs.
• Timers Keepalive/Hold: Keepalive interval is the time between keepalive messages sent to peers. Hold
time is the timeout after the last keepalive message until the peer is declared dead. The Keepalive interval
must be set in order to set the Hold time. All times are in seconds from 1 to 65535. Set to 0 or empty to
disable (default).
Networks Associated with ASN or IPv6 Networks Associated with ASN: To configure a BGP router, you need
an AS number. An AS number is an identification of autonomous system. BGP protocol uses the AS number for
detecting whether the BGP connection is internal one or external one. Use the IPv4 address and netmask or
IPv6 address with a CIDR notation
Neighbor Options or IPv6 Neighbor Options: Creates a new neighbor identified by remote ASN and IP address.
• Peer Group: Optionally specify a peer group
for this neighbor. You can Bind to an existing
peer group or Define a new one. A neighbor
will inherit the properties from the peer group
to which it is bound. Properties specified in a
neighbor will override inherited properties.
• IP Address: The IP address of the neighbor. Not
specified if this is a peer group definition.
• Port: Specify port.
• Remote ASN: Enter the ASN of the remote AS.
The AS (Autonomous System) number is one of
the essential elements of BGP. BGP is a distance
vector routing protocol, and the AS-Path
framework provides distance vector metric and
loop detection to BGP. RFC1930.
• Weight: Assign a weight to a neighbor
connection.
• Maximum Prefix: Specify the maximum number
of prefixes that a BGP routing process will
accept from the specified peer.
• Password: Enable message digest5 (MD5)
authentication on a TCP connection between
BGP peers. The same password must be used on
both peers.
• Update Source: Specify the IPv4 source address
or interface name to use for the BGP session to
this neighbor.
• Default Originate: Allow the local router to send
the default route (0.0.0.0) to a neighbor for use
as a default route. Optionally, a route map can
be specified to conditionally inject the default
route.
• Don't Send Community: Unless this option is
selected, any defined communities attributes will be sent to the BGP neighbor.
• eBGP Multihop: Accept and attempt BGP connections to external peers residing on networks that are not
directly connected. Mutually exclusive with TTL Security. Optionally specify Time To Live from 1 to 255
hops.
• TTL Security: Specify the number of hops to reach eBGP neighbors. Mutually exclusive with eBGP Multihop.
prefix length to define the address range.
