VPN Technologies – MPLS – Label Distribution Protocol

Time to tackle the VPN technologies part and this start with MPLS. In this first post, we will build a MPLS network using Label Distribution Protocol.   VPN Technologies – MPLS – Label Distribution Protocol – Theory:   Here are the link to the Cisco documentation regarding MPLS: http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_basic/configuration/15-mt/mp-basic-15-mt-book.html http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/mp_ldp/configuration/15-mt/mp-ldp-15-mt-book.html   VPN Technologies – MPLS […]

L2 technologies – Spanning-Tree Protocol

Here is one good topic. I’m going to have a look only at rapid-PVST+. The standard spanning-tree isn’t really used any more in Cisco networks.   L2 technologies – Spanning-Tree Protocol – Physical network diagram L2 technologies – Spanning-Tree Protocol – configuration: Let’s first make sure that rapid-PVST+ is enable on all switches. SW10(config)#spanning-tree mode […]
