The MPLS LDP Inbound Label Binding Filtering feature can be used to control the amount of

memory used to store Label Distribution Protocol (LDP) label bindings advertised by other

devices. For example, in a simple Multiprotocol Label Switching (MPLS) Virtual Private Network

(VPN) environment, the VPN provider edge (PE) devices might require label switched paths

(LSPs) only to their peer PE devices (that is, they do not need LSPs to core devices). Inbound

label binding filtering enables a PE device to accept labels only from other PE devices.

When doing mutual redistribution at multiple points (between OSPF and EIGRP on R1 & R2), we may create routing loops so we should use route-map to prevent redistributed routes from redistributing again into the original domain.

In the below example, the route-map “SET-TAG” is used to prevent any routes that have been redistributed into EIGRP from redistributed again into OSPF domain by tagging these routes with tag 1:

Let’s see how the “logging synchronous” command affect the typing command:

Without this command, a message may pop up and you may not know what you typed if that

message is too long. When trying to erase (backspace) your command, you realize you are

erasing the message instead.

With this command enabled, when a message pops up you will be put to a new line with your

typing command which is very

Once again, Cisco changed the IOS configuration commands required for OSPFv3 configuration. The new OSPFv3 configuration uses the “ospfv3” keyword instead ofthe earlier “ipv6 router ospf” routing process command and “ipv6 ospf” interface commands.

The Open Shortest Path First version 3 (OSPFv3) address families feature enables both IPv4 and IPv6 unicast traffic to be supported. With this feature, users may havetwo processes per interface, but only one process per address family (AF).
