In the Neighbor Password field, enter the password that should be used to connect to the neighbor peer. (Do not enter the customer AS number that was specified in the BGP router settings.) In the BGP Parameters section, enter the BGP AS number of the ISP.From the Enable BGP Routing Protocol Usage list, select yes.In the Neighbor IP field, enter the default gateway IP address of the existing provider.Enter a descriptive name for the network and then click OK.In the Neighbors table, add an entry for each provider network:.On the OSPF/RIP/BGP Settings page, click Neighbor Setup IPv4 from the Configuration menu in the left navigation pane.This ping dampening will occur whenever the BGP service goes up and down numerous times over a small period of time. Otherwise, the BGP routing infrastructure will dampen any ICMP request and response, and the BGP service will have to be restarted on the ISP side. You must start configuring the neighbor settings on the provider side only after you have completed the previous sections for enabling BGP, configuring the BGP router, and adding an IP prefix filter. Obtain and carefully verify the default gateway IP address for each provider. Then click OK.īefore you configure the neighbor settings, the network for each provider that participates in BGP routing must be configured properly. In the Network Prefix field, enter the network IP range that you received from the ARIN (in this example: 198.200.200.0/24 ).In the Sequence Number section, click + to add a sequence number configuration and specify a unique identifier number for the prefix list item in the Sequence Number field.In the IPv4 Prefix Filter configuration, enter an optional description.Enter a descriptive name, for example ARIN, and then click OK. In the IPv4 Prefix Filter table, add an entry for the IP prefix filter.For general information on the implementation of IPv6 on the Barracuda CloudGen Firewall, see IPv6. Note that IPv6 must also be enabled in FRR. ![]() When using IPv6, specify all settings described in the sections designated for IPv6. The Barracuda CloudGen Firewall also provides this configuration area for IPv6 addresses. On the OSPF/RIP/BGP Settings page, click Filter Setup IPv4 from the Configuration menu in the left navigation pane. Specify the logging details according to your requirements.On the OSPF/RIP/BGP Settings page, click BGP Preferences from the Configuration menu in the left navigation pane.If you want, you can configure more detailed logging, special routing tables, and multipath handling. In most cases, the default BGP preferences are sufficient and do not have to be configured. OSPF Routes – Network routes learned by the OSPF router will be redistributed.RIP Routes – Network routes learned by the RIP router will be redistributed.Connected Routes – Network routes of directly attached networks will be redistributed.You can enable the following network routes: In the Route Distribution Configuration section, enable the network route types to be redistributed by this BGP router according to your requirements.In the Network Prefix field, enter the network and subnet mask in CIDR notation for the autonomous system of the BGP router.Enter a name for the network and click OK.In the Networks table, add an entry for the ARIN network and any other network that you want to advertise. ![]() The password can consist of small and capital characters, numbers, and non-alpha-numeric symbols, except the hash sign (#). Usually, the first or last IP address in the subnet is used. You can enter any address from your ARIN range. In the Router ID field, enter the IP address of the BGP router.
