Command Syntax and Usage | |
---|---|
peer <peer number (1-16)> | |
Displays the BGP Peer menu used to configure each BGP peer. Each border router, within an autonomous system (AS), exchanges routing information with routers on other external networks. To view this menu, see /cfg/l3/bgp/peer <peer number> BGP Peer Configuration Menu. Default: enable | |
aggr <aggregate number (1-16)> | |
Displays the Aggregation menu. To view this menu, see /cfg/l3/bgp/aggr <aggregate number> BGP Aggregate Routing Configuration Menu. Default: enable | |
as <autonomous system number (1-65535.65535)|(1-4294967295)> | |
Sets the Autonomous System Number (ASN) for this autonomous system. An AS is the unit of a router policy, either a single network or a group of networks, that is controlled by a common network administrator on behalf of an administrative entity (such as a university, a business enterprise, or a business division). An AS is assigned a globally unique number called an ASN. An autonomous system shares routing information with other autonomous systems using the Border Gateway Protocol (BGP). Values: ![]() ![]() Default: 0 | |
asmode <2byte|4byte> | |
Sets the Autonomous System Number mode. Default: 4byte | |
asdot <d|e)> | |
Specifies whether to enable or disable AS DOT Notation (asdot). When disabled, the 4-byte values are represented in decimal format in the autonomous system number (as). Whereas when enabled, as is represented by a dot notation. This means that asdot represents as numbers less than 65536 using as plain notation and as numbers above 65536 using asdot. Default: disabled | |
advfip | |
Specifies whether to globally enable floating IP advertisement. Default: disabled | |
grcrstrt | |
Displays the BGP Graceful Restart menu. To view this menu, see /cfg/l3/bgp/grcrstrt BGP Graceful Restart Menu. Note: This option is only available if BGP mode FRR was selected (and after reboot). | |
mode <F-FRR | L-Legacy> | |
Specifies the BGP mode. Note: In Legacy mode, Alteon advertises local routing information with a fixed route distribution enabled for all IP masks except for a mask with a prefix length of 32 (255.255.255.255). Values: F-FRR, L-Legacy Default: Legacy Note: Changing the BGP mode requires a platform reboot. | |
stdclist | |
Displays the BGP Standard Community List menu. To view this menu, see /cfg/l3/bgp/stdclist BGP Standard Community List Menu. Note: This option is only available if BGP mode FRR was selected (and after reboot). | |
extclist | |
Displays the BGP Extended Community List menu. To view this menu, see /cfg/l3/bgp/extclist BGP Extended Community List Menu. Note: This option is only available if BGP mode FRR was selected (and after reboot). | |
larclist | |
Displays the BGP Large Community List menu. To view this menu, see /cfg/l3/bgp/larclist BGP Large Community List Menu. Note: This option is only available if BGP mode FRR was selected (and after reboot). | |
maxpath <max AS path length (1-127)> | |
Limits the maximum length of an accepted AS Path. Paths greater than this value are ignored. This is designed to protect the MP CPU, memory resources, and routing table from BGP-based attacks, BGP errors and probes designed to locate BGP speaking devices that do not limit the maximum AS Path. Default: 50 | |
pref <preference (0-4294967294)> | |
Sets the local preference. The path with the higher value is preferred. When multiple peers advertise the same route, use the route with the shortest AS path as the preferred route if you are using eBGP, or use the local preference if you are using iBGP. | |
scanfreq | |
Sets the scan frequency. Values: 1-120 | |
ecmp <ibgp|ebgp|eibcp|off> | |
ECMP (Equal Cost Multipath Protocol) for BGP enables Alteon to distribute egress IPv4 traffic between multiple next hop routers that have equal cost path to the destination. You can specify ECMP to work with different peer types or disable it. This configuration is only available when the FRR mode is on. Values: ![]() ![]() ![]() ![]() Default: off | |
on | |
Globally turns BGP on. | |
off | |
Globally turns BGP off. | |
cur | |
Displays the current BGP configuration. |
