Q1. What is routing?
Ans. 
Routing is the process of selecting the best path for network traffic to reach its destination.
• Routing involves determining the optimal path for data packets to travel from the source to the destination.

• Routers use routing tables to make decisions on how to forward packets based on destination IP addresses.

• Routing protocols like OSPF and BGP are used to exchange routing information between routers.

• Dynamic routing allow...read more

Q2. How to work ospf?
Ans. 
OSPF (Open Shortest Path First) is a routing protocol used to find the best path for data packets in a network.
• OSPF uses a link-state routing algorithm to determine the best path for data packets.

• Routers in an OSPF network exchange link-state advertisements (LSAs) to build a topology map of the network.

• OSPF calculates the shortest path to each network by using Dijkstra's algorithm.

• OSPF supports multiple areas to scale ...read more

Q3. What area 0 in ospf?
Ans. 
Area 0 in OSPF is the backbone area where all other areas connect.
• Area 0 is also known as the backbone area in OSPF.

• All other OSPF areas must connect to Area 0.

• Area 0 is required for OSPF to function properly.

• Area 0 is used to route traffic between different OSPF areas.

Q4. How to select DR/BDR in ospf?
Ans. 
DR/BDR in OSPF are selected based on their priority and router ID.
• DR/BDR election occurs on multi-access networks like Ethernet

• Priority value is used to determine the DR/BDR, default is 1-255

• Router with highest priority becomes DR, second highest becomes BDR

• If priorities are equal, router with highest router ID wins

• Priority can be manually configured to influence DR/BDR selection

Q5. What use of wait attributes in BGP?
Ans. 
Wait attributes in BGP are used to influence the route selection process by delaying the installation of a route into the IP routing table.
• Wait attributes are used to delay the installation of a route into the IP routing table until the wait timer expires.

• This can be useful in scenarios where a route should not be immediately installed, allowing time for other routes to be considered first.

• Wait attributes can help prev...read more

Q6. What is difference between OSPF and BGP?
Ans. 
OSPF is an interior gateway protocol used within a single autonomous system, while BGP is an exterior gateway protocol used between different autonomous systems.
• OSPF is a link-state routing protocol, while BGP is a path vector routing protocol.

• OSPF uses a shortest path first algorithm to determine the best path, while BGP uses policies and attributes to make routing decisions.

• OSPF is typically used within a single orga...read more

Q7. How to synchronise routing from ospf to bgp?
Ans. 
To synchronize routing from OSPF to BGP, redistribute OSPF routes into BGP and adjust metrics accordingly.
• Redistribute OSPF routes into BGP using route redistribution commands

• Adjust metrics to ensure BGP routes are preferred over OSPF routes

• Use route maps to filter and manipulate routes during redistribution
