What is split horizon on Frame Relay?
Split horizon issues are overcome through the use of logical subinterfaces assigned to the physical interface connecting to the Frame Relay network. A physical interface can be divided into multiple, logical interfaces. Each logical interface is individually configured and is named after the physical interface.
What is the split horizon rule?
Split horizon is a method used by distance vector protocols to prevent network routing loops. The basic principle is simple: Never send routing information back in the direction from which it was received.
Why would you use subinterfaces with Frame Relay?
Frame Relay provides a mechanism to allow a physical interface to be partitioned into multiple virtual interfaces. In a similar way, using subinterfaces allows a partially meshed network to be divided into a number of smaller, fully meshed point-to-point networks.
How do I enable split horizon in RIP?
Configure the split-horizon Option
- On switch 1, enter the configuration mode for the interface.
- Enter the configuration mode for the router.
- Enter the configuration mode for VLAN 1.
- Enable the split-horizon option.
- Review the configuration information.
What is the maximum hop count of routing information protocol?
15
Hop Count : The maximum hop count allowed for RIP is 15 and a hop count of 16 is considered as network unreachable.
Why does BGP not need split horizon?
The BGP split-horizon rule states that a BGP router that receives a BGP route via an iBGP peering shall not advertise that route to another router that is an iBGP peer. It is important that you commit this rule to memory. By doing so, you will be able to recognize when this is the reason for missing routes.
Does split horizon solve count to infinity problem?
As we see in the distance vector that is broadcast to node Y the end destination X has an infinity value. This solves the count-to-infinity problem since if the link between Y and Z will not bounce between each other and instead directly try another path.
What is Frame Relay used for?
Frame relay is commonly used to connect two or more LAN bridges over large distances. The iSeries system supports these frame-relay network connections: Frame relay direct network: Allows data that uses SNA or TCP/IP communications over a frame-relay network to move at speeds of up to 2.048 Mbps.
What is the difference between ripv1 and RIPv2?
RIP v1 is an older, no longer much used routing protocol. RIP v2 is a classless protocol and it supports classful, variable-length subnet masking (VLSM), CIDR, and route summarization. RIPv2 supports authentication of RIPv2 update messages (MD5 or plain-text).
What is RIPv2 protocol?
The Routing Information Protocol, version 2 (RIPv2) is an enhanced version of RIP that includes support for important routing features such as class-less addressing and variable-length subnet masks [37]. RIPv2 is a distance-vector protocol that has been in use for many years.
How is hop count calculated?
Open Command Prompt and then execute tracert followed by the hostname or IP address of the destination. Among other things, you’ll be shown the hops as they occur, with the last hop number being the total hop count.
