1 00:00:09,250 --> 00:00:17,110 One of the great attributes that she will see whenever you deal with static crowds or dynamic routing 2 00:00:17,110 --> 00:00:23,300 protocols such as rape or SPF is the administrative a distance. 3 00:00:23,620 --> 00:00:33,130 Now the administrative distance is a measure or a number that is used by routers to determine which 4 00:00:33,130 --> 00:00:38,200 shroud is the preferred route for the destination. 5 00:00:38,200 --> 00:00:41,910 The lower the number the better the route. 6 00:00:41,980 --> 00:00:50,460 If your 40 gauge has a connected network to it then the route to it is numbered 0. 7 00:00:50,560 --> 00:00:55,680 That is the best trunk is the rack that is connected directly to your forehead. 8 00:00:56,140 --> 00:01:06,260 If it has a static crowd as we have here it has an administrative distance of 10 and so it goes on our 9 00:01:06,380 --> 00:01:14,300 behalf is one hundred and ten and rape is one hundred and twenty. 10 00:01:14,320 --> 00:01:23,550 Now if we have two routes to the same destination the lower the administrative distance that is the 11 00:01:23,550 --> 00:01:25,370 route it will be chosen. 12 00:01:25,430 --> 00:01:34,070 So if we have one static crowd that is to the default trout that has an administrative distance of 10 13 00:01:34,190 --> 00:01:41,060 and we will configure now another staggered crowd to the same destination which is the default trout 14 00:01:43,970 --> 00:01:55,970 now will choose another interface went to art gate which will be turned to that ninety nine now will 15 00:01:55,970 --> 00:02:01,980 choose a bigger administrative distance. 16 00:02:02,030 --> 00:02:10,280 So now we have two static rounds to the same destination one with the administrative distance of 20 17 00:02:10,790 --> 00:02:14,690 and one with administrative distance of 10. 18 00:02:14,750 --> 00:02:23,750 Now if we will use the get router info routing table 19 00:02:28,790 --> 00:02:31,650 0 take a look. 20 00:02:31,650 --> 00:02:43,410 The only static crowd the leads are packets to the default trust is the static crowd that was configure 21 00:02:43,860 --> 00:02:46,890 with the administrative distance of 10. 22 00:02:46,980 --> 00:02:57,600 That is the best match route that 48 finds whenever it sees packets for destined to the default route 23 00:02:58,440 --> 00:03:11,100 if we will use the database instead instead of all we will see the whole routing table which also includes 24 00:03:11,480 --> 00:03:14,960 the one the new route that we have just configure. 25 00:03:15,510 --> 00:03:20,860 But as you can see the only one that is active is that static route.
