Q2. What is bgp path selection process
Ans. 
BGP path selection process determines the best path for routing based on various attributes.
• BGP selects the path with the highest weight attribute first

• If weights are the same, BGP looks at the local preference attribute

• Next, BGP considers the AS path length

• BGP then checks the origin code attribute

• After that, BGP looks at the MED (Multi-Exit Discriminator) attribute

• If all else is equal, BGP chooses the path with the lo...read more

Q3. What is stub area
Ans. 
A stub area is an OSPF area that does not contain external routes.
• Stub areas reduce the amount of routing information exchanged within an OSPF network.

• Stub areas use a default route to reach external networks.

• Stub areas are commonly used to reduce the size of the OSPF database and improve network performance.
