From the exhibit we see: OSPF packet ignored: area mismatch

IS-IS hello PDUs establish adjacencies with other routers and have three different formats: one for point-to-point hello packets, one for Level 1 broadcast links, and one for Level 2 broadcast links. Level 1 routers must share the same area address to form an adjacency, while Level 2 routers do not have this limitation.

In LANs, the election of the designated router takes place when the OSPF network is initially established.
When the first OSPF links are active, the routing device with the highest router identifier (defined by the router-id configuration value, which is typically the IP address of the routing device, or the loopback address) is elected the designated router. The routing device with the second highest router identifier is elected the backup designated router.

The asterisk (*) next to one of the block entries corresponds to the active route that is used for new traffic.
The term 'new traffic' corresponds to a single packet or an entire flow to a destination, depending on the type of switching configured.

Many Juniper Networks EX Series switches support the Virtual Chassis flexible, scaling switch solution.
You can connect individual switches together to form one unit and manage the unit as a single chassis.

Note: The higher the priority value, the greater likelihood the routing device will become the designated router. By default, routing devices have a priority . A priority of 0 marks the routing device as ineligible to become the designated router. A priority of 1 means the routing device has the least chance of becoming a designated router. A priority means the routing device is always the designated router.

This example shows how to configure the storm control level on interface ge-0/0/0 by setting the level to a traffic rate ,000 Kbps, based on the traffic rate of the combined applicable traffic streams. To configure storm control: Specify the traffic rate in Kbps of the combined traffic streams on a specific interface: [edit ethernet-switching-options] user@switch# set storm-control interface ge-0/0/0 bandwidth 15000

Use the link aggregation feature to aggregate one or more links to form a virtual link or link aggregation group (LAG).

Explanation; Type internal in group two indicates refers to an IBGP route.

A: The fourth LSA type, network example:

In this example we have R1 that is redistributing information from the RIP router into OSPF. This makes
R1 an ASBR (Autonomous System Border Router). What happens is that R1 will flip a bit in the router LSA to identify itself as an ASBR. When R2 who is an ABR receives this router LSA it will create a type 4 summary ASBR LSA and flood it into area 0. This LSA will also be flooded in all other areas and is required so all OSPF routers know where to find the ASBR.
B: Example:

Router 2 can create a Type 3 summary LSA and flood it into area 0. This LSA will flood into all the other areas of our OSPF network. This way all the routers in other areas will know about the prefixes from other areas. Note: The name "summary" LSA is very misleading. By default, OSPF is not going to summarize anything for you. There is however a command that let you summarize inter-area routes. Take a look at my OSPF summarization tutorial if you are interested. If you are looking at the routing table of an OSPF router and see some O IA entries, you are looking at LSA type 3 summary LSAs. Those are your inter-area prefixes!

The default Ethernet MTU is 1500. There is a 24 byte GRE overhead, so there remain 1476 bytes for the data packet.
