1 00:00:00,590 --> 00:00:08,060 In the section we're gonna talk about jail BP protocol Gateway log balancing protocol jail. 2 00:00:08,060 --> 00:00:15,170 BP is a Cisco proprietary protocol that attempts to overcome the limitations of existing redundant rather 3 00:00:15,170 --> 00:00:21,140 protocols by adding basic load balancing feature. 4 00:00:21,140 --> 00:00:28,040 There are two roles in jail BP or for others and they are active virtual Gateway and active virtual 5 00:00:28,370 --> 00:00:30,110 forwarders. 6 00:00:30,110 --> 00:00:33,840 The first one in the active virtual gateway. 7 00:00:33,890 --> 00:00:40,710 Members of the jail BP Group select it rather as active future will get way from among themselves. 8 00:00:40,910 --> 00:00:49,280 Other group members with in the standby to take action when a G is in accessible active which you'll 9 00:00:49,280 --> 00:00:57,690 get by a size of a virtual Michael rest for each member of jail BP Group one of the main tasks of active 10 00:00:57,690 --> 00:01:04,460 virtual get made is to listen to art requests that are towards the default gateway IP address and respond 11 00:01:04,460 --> 00:01:11,390 to this request with the MAC address of jailed BP group members thus active free you'll get. 12 00:01:11,480 --> 00:01:20,150 Also provides load sharing between members and each Gateway is responsible for forwarding packets sent 13 00:01:20,150 --> 00:01:28,340 by virtual MAC address assigned by the active virtual Gateway and this gateways are called active virtual 14 00:01:28,550 --> 00:01:31,440 forwarders within the GOP group. 15 00:01:31,460 --> 00:01:40,090 There can be up to four active virtual forwarders and you are the states of jail BP. 16 00:01:40,100 --> 00:01:48,500 We have different states for virtual Gateway and virtual forwarders for virtual Gateway disabled means. 17 00:01:48,500 --> 00:01:56,010 There is a part of the geographic configuration but the virtual IP is not configured or learned. 18 00:01:56,180 --> 00:02:03,010 Initial means which you IP is configured or learned but the configuration is not yet complete. 19 00:02:03,140 --> 00:02:11,360 The corresponding interface must be in operational in layer 3 and should be capable of IP routing. 20 00:02:11,840 --> 00:02:18,920 The lesson means hello packets are reserved by the virtual Gateway pigments which will get wet through 21 00:02:18,920 --> 00:02:23,450 us to be active or stand by stand by means gateway. 22 00:02:23,450 --> 00:02:26,830 In this case is ready to be active virtual gateway. 23 00:02:26,840 --> 00:02:32,300 In the case there is a problem in the active virtual Gateway active means. 24 00:02:32,420 --> 00:02:39,890 This Gateway is active virtual Gateway and response to the ARP request made to the virtual IP address. 25 00:02:40,310 --> 00:02:46,910 And let's take a look to the for virtual forward states state's initial means the virtual mac address 26 00:02:46,910 --> 00:02:53,660 has been learned but the virtual forward configuration is not yet completed through later the interface 27 00:02:53,660 --> 00:02:58,180 can work in Layer 3 and must be capable of IP routing. 28 00:02:58,460 --> 00:03:00,860 Listen means the virtual forward. 29 00:03:00,950 --> 00:03:07,910 In this case guess the help packets and is ready to go in the active state if the current active virtual 30 00:03:07,910 --> 00:03:16,650 move forward becomes inaccessible and the active statements the device is in the active state is active. 31 00:03:16,640 --> 00:03:24,020 Virtual forwarders and it's responsible to respond to packets arriving to the virtual forward mac address 32 00:03:27,110 --> 00:03:29,250 and here is the configuration of the. 33 00:03:29,250 --> 00:03:33,140 BP Let's take a look. 34 00:03:33,280 --> 00:03:37,330 It's almost same with the we are happy and the jail BP. 35 00:03:37,330 --> 00:03:43,200 As you can see that we go in the under the interface mode we assign an IP address. 36 00:03:43,780 --> 00:03:51,110 Then we assign the geo BP and geo BP group number and IP of the jail BP address. 37 00:03:51,130 --> 00:03:54,670 Then we can define priority and preemption as well 38 00:03:57,730 --> 00:04:01,290 we have three GOP pillow balancing options. 39 00:04:01,300 --> 00:04:09,520 They are weighted host dependent and their round robin let's take a look to the waiter first. 40 00:04:09,520 --> 00:04:17,920 The Lord sent to rather we rise depending on the vet Molly advertised but by the rather in the state. 41 00:04:18,960 --> 00:04:23,790 In the host dependent a host is granted to use the same virtual mac address. 42 00:04:23,790 --> 00:04:32,940 As long as the virtual MAC address joins the GOP group and in the round robin a load balancing algorithm 43 00:04:33,270 --> 00:04:40,080 which each virtual forward response to incoming ARP requests for every actual IP address. 44 00:04:40,380 --> 00:04:44,730 And please keep in mind that this is the default algorithm 45 00:04:47,300 --> 00:04:50,900 and here is the authentication of GBP GBP. 46 00:04:50,960 --> 00:05:01,040 Also supports the MDA five and you can use GBP GBP group member authentication and the five and key 47 00:05:01,040 --> 00:05:01,550 string. 48 00:05:01,550 --> 00:05:11,080 And this is the string that we're gonna use for authentication and you can also make the jail BP object 49 00:05:11,100 --> 00:05:12,140 talking too. 50 00:05:12,150 --> 00:05:19,140 And here is the configuration how you can do it and that's the same logic between the H SRP and we are 51 00:05:19,140 --> 00:05:19,540 IP.
