Some Interesting Questions


#1

Hello there. I am new in Vyos, so I need some answers. On the picture is given the output of the command: (picture is in attachment)

What is the 1.1.1.1?

1.Region in which is routed
2. Mandatory identifier from neighboring router
3. IP address of the neighboring router


#2

It is the ID of the neighbor, which is one of it’s IP address.

It can be either explicitly set in the OSPF config, otherwise it is the loopback address, or if loopback is not set, the smaller IP address of the system (I think, unsure of this one, could also be the IP address of the interface participating in the ospf process)


#3

JFL thanks for answering. OK, here is my next question. The output of the command is in attachment.

With the exception of the entrance to the local loop (C>* ::1/128), why the router has four additional directly connected networks?

  1. Each router interface has two IPv6 addresses (local and global)
  2. The Networks are learned through routing protocols
  3. The router has four interfaces
  4. These are additional static routes

Answer 1.

Is this a quiz ? :smiley:


#5

Thereabouts :smiley: I make questions about vyatta operating system and in this way I learn new things. You’re doing great with answers :smiley: There will be more questions in coming days. Merry Christmas and Happy New Year to everyone!

The Network topology is shown on the picture (in attachment). After connecting and setting the interface addresses, which command is specified static route on the router R1 with which the traffic from the host with address 192.168.60.2 would able to come to host 192.168.60.130?

  1. vyatta@R1# set protocols static route 192.168.60.128/26 next-hop 192.168.60.129

  2. vyatta@R1# set protocols static route 192.168.60.130 next-hop 192.168.60.65

  3. vyatta@R1# set protocols static route 192.168.60.128/26 next-hop 192.168.60.65

  4. vyatta@R1# set protocols static route 192.168.60.129 next-hop 192.168.60.65

  5. vyatta@R1# set protocols static route 192.168.60.128/26 next-hop 192.168.60.66

In the routing table appear two routes to the same network. One is marked with O, and the other with R. Which route is used to forward traffic to the network?

  • Both routes will be equally used
  • The route with a R
  • It depends on the metric that is specific for each route
  • The route with a O
