BEAM iSERIES WebUI - Routing




Summary

This chapter is an overview of the Routing section in BEAM iSERIES devices.

Static Routes

Static routes specify over which interface and gateway a certain host or network can be reached. In this page you can configure your own custom routes.



 Field Name
 Value  Description
 Routing table  Main | WAN | WAN2 | WAN3; Default: WAN  Defines which table will be used for the route in question
 Interface  LAN | WAN(wired) | WAN2(Mobile) | WAN3(WiFi) | VPN instances; Default: WAN(wired)  The zone where the target network resides
 Destination address*  ip; Default: 0.0.0.0  The address of the destination network
 Netmask*  ip; Default: 0.0.0.0  A Mask that is applied to the Target to determine to what actual IP addresses the routing rule applies
 Gateway  ip; Default: " "  Defines where the router should send all the traffic that applies to the rule
 Metric   integer; Default: 0  The Metric value is used as a sorting measure. If a packet about to be routed fits two rules, the one with the higher metric is applied

*Additional notes on Destination & Netmask:

You can define a rule that applies to a single IP like this: Destination - some IP; Netmask - 255.255.255.255. Furthermore, you can define a rule that applies to a segment of IPs like this: Destination – some IP that STARTS some segment; Netmask – Netmask that defines how large the segment is. e.g.:

 Field Name
 Value  Description
 192.168.55.161  255.255.255.255  Only applies to 192.168.55.161
 192.168.55.0   255.255.255.240  Applies to IPs in the 192.168.55.0 - 192.168.55.255
 192.168.55.240   255.255.255.240  192.168.55.240 - 192.168.55.255
 192.168.55.161   255.255.255.0  192.168.55.0 - 192.168.55.255
 192.168.0.0   255.255.0.0  192.168.0.0 - 192.168.255.255

Static ARP entries

Static ARP entries are used to bind a MAC address to a specific IP address. For example, if you want a device to get the same IP every time it connects to the router, you can create a Static ARP entry by binding that device’s MAC address to the desired IP address. The router will then create an entry in the ARP table, which in turn will make sure that that device will get the specified IP address every time.


Dynamic Routes

BGP Protocol

Border Gateway Protocol (BGP) is a standardized exterior gateway protocol designed to exchange routing and reachability information among autonomous systems (AS) on the Internet. The protocol is often classified as a path vector protocol but is sometimes also classed as a distance-vector routing protocol. The Border Gateway Protocol makes routing decisions based on paths, network policies, or rule-sets configured by a network administrator and is involved in making core routing decisions.

General Settings



 Field Name
 Value  Description
 Enable  yes | no; Default: no  Toggles the BGP protocol ON or OFF
 Enable vty  yes | no; Default: no  Toggles vty access from LAN ON or OFF
 Import config  -  Uploads an external BGP configuration

BGP Instance


 Field Name
 Value  Description
 Enable  yes | no; Default: no  Toggles the BGP instance ON or OFF
 AS  integer: " "  AS number is an identification of an autonomous system. BGP protocol uses the AS number for detecting whether the BGP connection is an internal one or external one. [Required]
 BGP router ID  string; Default: " "  The router id is used by BGP to identify the routing device from which a packet originated. Default router ID value is selected as the largest IP Address of the interface.
 Network  string; Default: " "  Add an announcement network(s)

BGP Peers


 Field Name
 Value  Description
 Enable  yes | no; Default: no  Toggles the BGP peer ON or OFF
 Remote AS  integer: " "  Neighbour's remote AS
 Remote address  ip; Default: " "  Neighbour's remote IPv4 address

Access List Filters


 Field Name
 Value  Description
 Enable  yes | no; Default: no  Toggles the Access filter ON or OFF
 Peer  bgp peer; Default: first peer on list  Applies the rule for the specified peer
 Action  Permit | Deny; Default: Permit  Denies or permits matched entry
 Network  Any | ip; Default: Any  Applies filter rule for this source network
 Direction  Inbound | Outbound;
 Default: Inbound
 If direction is Inbound, the access list is applied to input routes. If direction is Outbound the access list is applied to advertised routes

RIP Protocol

The Routing Information Protocol (RIP) is one of the oldest distance-vector routing protocols which employ the hop count as a routing metric. RIP prevents routing loops by implementing a limit on the number of hops allowed in a path from source to destination. The maximum number of hops allowed for RIP is 15, which limits the size of networks that RIP can support. A hop count of 16 is considered an infinite distance and the route is considered unreachable. RIP implements the split horizon, route poisoning and holddown mechanisms to prevent incorrect routing information from being propagated.

OSPF Protocol

Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing (LSR) algorithm and falls into the group of interior gateway protocols (IGPs), operating within a single autonomous system (AS). It is defined as OSPF Version 2 in RFC 2328 for IPv4.
