You can create up to 512 multilink groups on each Cisco 10000 series ESR.Step 1 To create a new multilink group, enter the interface multilink command. In the following example, the multilink group is assigned the number 8, but it can be any number from 1 to 2147483647.Router(config)# interface multilink 8Router(config-if)# Note You also use the interface multilink number command to enter interface configuration mode for an already existing multilink group.Step 2 Use the ppp chap hostname command to assign a name that is used when you add T1 interfaces to the group. For example:Router(config-if)# ppp chap hostname cambridgeStep 3 To create an IP address for the multilink group, use the ip address command. For example:Router(config-if)# ip address 172.27.48.209 255.255.0.0Step 4 Add any other configuration subcommands required for the enabling of routing protocols and adjust the interface characteristics.Step 5 Exit out of interface configuration mode.Router(config-if)# exitRouter(config)#After creating the multilink group, you can assign T1 interfaces to it. Note Multilink fragmentation is not supported on the Cisco 10000 series ESR. You must disable fragmentation on the remote end of the connection.Adding T1 Lines to a Multilink GroupThis section tells you how to add T1 interfaces to a multilink group. A multilink group consisting of multiple T1 interfaces is referred to as a multilink bundle.You should assign only full T1 interfaces to a multilink group. You cannot assign more than ten T1 interfaces to a multilink group.Step 1 Enter interface configuration mode for one of your T1 interfaces. The following example shows the command for entering a T1 interface on a CT3 line card:Router(config)# interface serial 3/0/0/1:0Step 2 If you have not already done so, specify the interface encapsulation as PPP.Router(config-if)# encapsulation pppStep 3 Enter the ppp multilink command to enable this interface to support MLP.Router(config-if)# ppp multilinkStep 4 Assign this interface to the multilink group. In this example, the interface is assigned to multilink group 8.Router(config-if)# multilink-group 8Step 5 Specify the PPP CHAP hostname. The hostname should be the same as the one assigned when you created the multilink group in the "Creating a New Multilink Group" section.Router(config-if)# ppp chap hostname cambridgeStep 6 Exit out of interface configuration mode.Router(config-if)# exitRouter(config)#If the interface you added to the multilink bundle contains information such as an IP address, routing protocol, or access list, the router ignores that information. If you remove the interface from the multilink bundle, that information becomes active again.To add more T1 interfaces to an already created multilink bundle, repeat Step 1 through Step 6. Tip To move a T1 line to a different MLP bundle, follow the above procedure. Be sure to change the multilink-group number in Step 4 and the hostname value in Step 5.Removing an Interface from a Multilink BundleTo remove an interface from a multilink bundle, use the procedure described in this section.Step 1 Enter interface configuration mode for the T1 interfaces you want to remove from a multilink bundle. For example:Router(config)# interface serial 3/0/0/1:0Step 2 Remove the interface from the multilink group.Router(config-if)# no multilink-groupStep 3 Disable multilink for the interface.Router(config-if)# no ppp multilinkStep 4 Remove the PPP authentication.Router(config-if)# no ppp chap hostnameStep 5 Exit out of interface configuration mode.Router(config-if)# exitRouter(config)#After you remove PPP authentication, the interface is completely removed from the multilink bundle.Show CommandsThis section lists show commands you can use to obtain information about multilink bundles.show interfaces multilinkUse the show interfaces multilink command to obtain statistics on a multilink bundle.Example:Router# show interfaces multilink 8Multilink8 is up, line protocol is upHardware is multilink group interfaceInternet address is 100.1.1.1/24MTU 1500 bytes, BW 15360 Kbit, DLY 100000 usec, rely 255/255, load1/255Encapsulation PPP, crc 16, loopback not setKeepalive not setDTR is pulsed for 2 seconds on resetLCP Open, multilink OpenOpen:IPCPLast input 15:24:43, output never, output hang neverLast clearing of "show interface" counters 15:27:59Queueing strategy:fifoOutput queue 0/40, 0 drops; input queue 0/75, 0 drops5 minute input rate 0 bits/sec, 0 packets/sec5 minute output rate 0 bits/sec, 0 packets/sec36 packets input, 665 bytes, 0 no bufferReceived 0 broadcasts, 0 runts, 0 giants, 0 throttles0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort31 packets output, 774 bytes, 0 underruns0 output errors, 0 collisions, 0 interface resets0 output buffer failures, 0 output buffers swapped out0 carrier transitionsshow ppp multilinkUse the show ppp multilink command to obtain information about all existing multilink bundles and their member links.Example:Router# show ppp multilinkMultilink8, bundle name is group1Bundle is Distributed0 lost fragments, 0 reordered, 0 unassigned, sequence 0x0/0x9rcvd/sent8 discarded, 4 lost received, 1/255 loadMember links:10 active, 0 inactive (max 10, min not set)Serial3/0/0/1:0Serial3/0/0/2:0Serial3/0/0/3:0Serial3/0/0/4:0 ...show interfaces multilink statUse the show interfaces multilink group-number stat command to review traffic statistics for a multilink bundle.Example:Router# show interfaces multilink 8 statMultilink 8Switching path Pkts In Chars In Pkts Out Chars OutProcessor 36 665 31 774Route cache 0 0 0 0Total 36 665 31 774
