im trying to make sense of
a.. routing table ? is it? to complete a homework question but i just dont understand can someone please explain? i sort of understand the jist of them but like, each line is another hop right> from, where to where tho? i also dont understand why 2 detinations would say default and why thered be a 0.0.0.0
couldnt find it in the book for the life of me
also user vs perm?? ugh ;/
Could you post the results of your routing table as text, many companies block photobucket and other meda sharing sites.
0.0.0.0 could mean a few things depending on where it shows up, if its "destination network" then it usually means a default gateway or a gateway of last resort. If a router can not find an entry in its routing table for a destination network then it'll send it over whichever path is marked with 0.0.0.0
That can not be a functional routing table, its missing entries. Is this for some homework or made up theoretical situation? Also is this a Juniper router? It really seems like the format a Juniper use's for its tables vs what a linux or Cisco system would use.
I'm not a Juniper expert but its looking like it does the following,
Packet destination is,
forward to 188.8.131.52 unicast through ge-0/0/1.0
forward to 184.108.40.206 unicast through ge-0/0/2.0
metric is 534
172.19.0.0/16 forward to 220.127.116.11 through ge-0/0/3.0
metric is 535
if not in table use
0.0.0.0/32 to MAC 0:17:cb:4e:ae:81 through ge-0/0/0.0 (this is the router itself)
But it discards any packet it doesn't know where to send it to,
default perm 0 rjct 36 1
0.0.0.0/32 perm 0 dscd 34 1
Also "user" entries are dynamically created entries from the routing daemon, usually from a neighbor router.
Whatever this is for its not getting to the internet ever, its only routing packets to those internal networks. And even then the order is off,
A packet who's destination is 172.19.52.20 should be routed out 172.19.52.16 ge-2.0, but instead it'll be routed out 172.19.52.0/24 and ge-1.0. The metrics would need to be rearranged to fit the correct order (unless ge-1.0 also services the network for ge-2.0).
