  OSPF route redistribution is definitely an important topic on the BSCI exam, and it is a topic saturated in details and defaults that you need to learn for the exam room and the job. To assist you move the BSCI examination, here's a quick overview of some of the OSPF route redistribution fundamentals.
  
  To determine if a modem can be an ABR o-r ASBR, run show ip ospf. If you are concerned by politics, you will seemingly hate to discover about the best. For supplementary information, please take a view at: phlebotomy wages. This also demonstrates any channels being redistributed into OSPF on this switch.
  
  R1#show ip ospf
  
  Routing Process "ospf 1" with ID 1.1.1.1
  
  Supports only solitary TOS( TOS0) tracks
  
  Supports opaque LSA
  
  It's an border and autonomous system border router
  
  Redistributing External Routes from,
  
  Linked, includes subnets in redistribution
  
  rip, includes subnets in redistribution
  
  When redistributing RIP in to OSPF, the option is needed to contain subnets in redistribution. A seed metric must be given, when redistributing OSPF into RIP. Browse here at the link open in a new browser window to check up the inner workings of this activity. (OSPF gives redistributed routes a default metric of 20 this could be changed, but a seed metric doesn't have to be set.)
  
  R1( config )#router ospf 1
  
  R1( config-router )#redistribute connected
  
  % Only classful communities is going to be reassigned
  
  R1( config-router )#redistribute linked subnets
  
  R1( config-router )#redistribute rip subnets
  
  R1( config-router )#router rip
  
  R1( config-router )#redistribute connected metric 1
  
  R1( config-router )#redistribute ospf 1 metric 1
  
  Automatically, routes redistributed into OSPF are marked as E2 routes. The metric for these tracks shows only the cost of the path from the ASBR to the destination network and doesn't contain the cost of the path from the local router to the ASBR. By comparison, E1 paths include the expense of the entire route from the local modem to the destination system.
  
  O E2 5.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0
  
  6.0.0.0/32 is subnetted, 1 subnets
  
  E E2 6.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0
  
  172.12.0.0/16 is variably subnetted, 2 subnets, 2 goggles
  
  O E2 172.12.21.0/30 [110/20] via 172.34.34.3, 00:33:32, Ethernet0
  
  O E2 7.1.1.1 [110/20] via 172.34.34.3, 00:33:21, Ethernet0
  
  15.0.0.0/24 is subnetted, 1 subnets
  
  E E2 15.1.1.0 [110/20] via 172.34.34.3, 00:33:32, Ethernet0
  
  To redistribute routes in to OSPF and mark them as E1 upon redistribution, make use of the metric-type selection with the redistribution order.
  
  R1( config )#router ospf 1
  
  R1( config-router )#redistribute rip subnets metric-type??
  
  1 Set OSPF External Typ-e 1 measurements
  
  2 Set OSPF External Typ-e 2 measurements
  
  R1( config-router )#redistribute rip subnets metric-type 1
  
  Go through the same two routes in R4's routing table, which are now shown as E1 routes:
  
  O E1 5.1.1.1 [110/94] via 172.34.34.3, 00:04:13, Ethernet0
  
  6.0.0.0/32 is subnetted, 1 subnets
  
  O E1 6.1.1.1 [110/94] via 172.34.34.3, 00:04:14, Ethernet0
  
  Making your CCNP certification and bsci exam success depends on understanding the details, and there are many of details involved in OSPF route redistribution! Keep studying, practice different cases in-your CCNA / CCNP home lab o-r tray rental, and you'll master these facts and pass the test!.
