6.4.5. BGP
The BGP tab allows to set up peerings of the NetModule AG router with other Border Gateway Protocol
enabled routers.
Parameter BGP General Settings
Administrative status Specifies whether the BGP routing protocol is active
Router ID Optionally the router ID can be defined in form of a dotted IPv4 rep-
resentation like 1.2.3.4. If the ID is omitted, the BGP daemon will try
to determine a valid value or fall back to 0.0.0.0
AS number The number of the autonomous system to which the NetModule
AG router belongs (1-4294967295)
Redistribute connected
routes
Redistribute routes to networks which are directly connected to the
NetModule AG router
Redistribute local routes Redistribute routes from the NetModule AG router’s own routing table
Redistribute OSPF routes Redistribute routes learned via the OSPF routing protocol
Disable when redundancy
backup
Disables the BGP protocol when the router is set to slave mode by
the VRRP redundancy protocol
Keepalive timer The interval in seconds of sending keepalive message
Holddown timer The time in seconds how long the router will wait for incomming BGP
messages until the router will assume the neighbor is dead
The neighbors tab is used to configure all the BGP routers to peer with.
Parameter BGP Neighbors
IP address IP address of the peer router
As number Autonomous system number of the peer router (1-4294967295)
Password Password for authentication with the peer router. If left blank authen-
tication is disabled.
Multihop Allow multiple hops between this router and the peer router instead of
requiring the peer to be directly connected.
Address Family Select whether ipv4-unicast or l2vpn-evpn address family shall be en-
abled
Weight This parameter specifies the default weight for the neighbor route
The Networks tab allows to add IP network prefixes that shall be distributed via BGP in addition to the
networks that are redistributed from other sources as defined on the general tab.
Parameter BGP Networks
Prefix Prefix of the network to be distributed
