How do I set BGP weight?

How do I set BGP weight?

BGP Weight Attribute Configuration

1. Prefer the path with the highest Weight – Both Weights are equal so move onto step2.
2. Prefer the path with the highest Local Preference – Local preference is the same for both routes.
3. Prefer the path that was locally originated – Same for both.

How do I change weight attributes in BGP?

How to Configure BGP Weight Attribute

1. Weight is the first BGP attribute in the list.
2. Cisco proprietary so you won’t find it on other vendor routers.
3. Weight is not exchanged between BGP routers.
4. Weight is only local on the router.
5. The path with the highest weight is preferred.

What is BGP default weight?

0
The weight attribute is a Cisco proprietary technology and considered as first attribute in BGP. The default value of weight is 0 and the range is from 0 to 65535.

How is the weight attribute used in BGP?

The BGP Weight Attribute Weight is a value that is assigned to our prefixes as a locally significant value. Weight is a simple number in the range of 0 through 65535, and the higher the weight value, the higher the preference for that path. When the prefix is locally generated, it will get a weight of 32768.

Does BGP load balance?

BGP implements load balancing through route recursion and route selection.

What is the default weight of a route if it is learned from an Ebgp neighbor?

By default the learned routes has a Weight value 0. This default value is 32768 for locally injected routes. Let’s give an example for each of these ways. You can also test yourself on BGP Quizes Section for your BGP Path Attribute knowledge.

How does BGP choose the best path?

The following parameters are followed for BGP’s path selection:

1. Prefer the highest local-preference value.
2. Prefer the shortest AS-path length.
3. Prefer the lowest origin value.
4. Prefer the lowest MED value.
5. Prefer routes learned from an EBGP peer over an IBGP peer.
6. Prefer best exit from AS.

What is metric in BGP?

MED (or metric) is the sixth BGP attribute: MED can be used to advertise to your neighbors how they should enter your AS. MED is exchanged between autonomous systems. The lowest MED is the preferred path. MED is propagated to all routers within the neighbor AS but not passed along any other autonomous systems.

Is EIGRP Still Cisco proprietary?

EIGRP is a routing protocol that is proprietary to Cisco. Although Cisco submitted a portion of EIGRP to the IETF for consideration as a potential standard, the entire protocol has not been accepted as a standard and remains proprietary to Cisco.
