Tech Tip:
How Much Memory Does Each BGP Route Consume?

Each Border Gateway Protocol (BGP) entry takes about 240 bytes of memory in the BGP table and another 240 bytes in the IP routing table. Each BGP path takes about 110 bytes.

http://www.cisco.com/warp/customer/459/
(available to registered users)

http://www.cisco.com/warp/public/459/
(available to non-registered users)

Sample Configurations:
Sample Configuration for BGP with Two Different Service Providers (Multihoming)

When running Border Gateway Protocol (BGP) with more than one service provider, you run the risk of having your autonomous system (AS) becoming a transit AS. This results in Internet traffic passing through your AS and potentially consuming all the bandwidth and resources on your router's CPU.

http://www.cisco.com/warp/customer/459/27.html

(available to non-registered users)

Sample Configurations:
Sample Configuration for iBGP and eBGP With or Without a Loopback Address

You can configure Border Gateway Protocol (BGP) either within an autonomous system or between different autonomous systems. When run within an autonomous system, it's called internal BGP (iBGP). When run between different autonomous systems, it's called external BGP (eBGP). Following are the sample configurations for iBGP and eBGP, both with and without a loopback address.

Sample Configurations:
Sample Configuration for Authentication in OSPF

This document shows sample configurations for OSPF authentication. OSPF supports both plain text and MD5 authentication. When you configure authentication, you must configure an entire area with same type of authentication. Starting in Cisco IOS( 12.0.8, authentication is supported on a per-interface basis.

Tech Tip:
BGP Path Selection Criteria

Border Gateway Protocol (BGP) bases its decision-making process on attribute values. When faced with multiple routes to the same destination, BGP chooses the best route toward the destination. This document summarizes how BGP chooses the best route.

Tech Tip:
Why Do BGP Neighbors Toggle between Idle, Connect, and Active States?

When establishing a Border Gateway Protocol (BGP) session, BGP goes through several state changes before reaching the final state, established. When a BGP neighbor toggles between the idle and active states during the normal progression of establishing a BGP session, there's a problem. Following are several reasons for this problem; the most common ones are discussed in this document.

Tech Tip:
What Does the "Adv router not-reachable" Error Message Mean?

When you see the following error message on the top of a link-state advertisement (LSA) it means that the router advertising the LSA isn't reachable through OSPF. There are several reasons for this message, most of which deal with misconfiguration or a broken topology. This document explains some of the more common reasons for this error message.

White Paper:
Route Selection in Cisco Routers

One of the intriguing aspects of Cisco routers, especially for those new to routing, is how the router chooses which route is the best among those presented by routing protocols, manual configuration, and various other means. While route selection is much simpler than you might imagine, understanding it completely requires some knowledge about the way Cisco routers work.

Security Advisory:
Cisco Catalyst Enable Password Bypass Vulnerability

Cisco Catalyst software permits unauthorized access to the enable mode in the 5.4(1) release. Once initial access is granted, access can be obtained for the higher level "enable" mode without a password. This problem is resolved in version 5.4(2). Customers with vulnerable releases are urged to upgrade as soon as possible.

Sample Configurations:
Sample Configuration: HSRP with Interface VLANs

In this configuration, there are two Catalyst 6509 switches, each with two multilayer switch feature cards (MSFCs), for a total of four routers. Our strategy is to have the MSFC-a1 in the diagram below route for odd virtual LANs (VLANs), as the primary router, and MSFC-b1 to route odd VLANs as the backup router. For even VLANs, we want MSFC-b2 to be the primary router and MSFC-a2 to be the backup router.

Sample Configurations:
X.25 PVC to SVC Configurations

Permanent Virtual Circuit or Connection (PVC) is a virtual circuit that is permanently established. PVCs save bandwidth associated with circuit establishment and tear down in situations where certain virtual circuits must exist all the time. Switched Virtual Circuit (SVC) is a virtual circuit that is dynamically established on demand and is torn down when transmission is complete. SVCs are used in situations where data transmission is sporadic.
