    Configuring GTP Services on a Peer Group

    You can configure GTP services to overwrite default configurations for a group of SGSN or S-GW peers.

    To configure GTP services on a peer group:

    1. Specify a name for the peer group.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp]user@host# edit peer-groups peer-grp-1
    2. Specify the name of the routing instance to which all peers in the peer group belong.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set routing-instance vrf-instance-peers-green
    3. Configure the IP addresses for the peers in the peer group.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set peer 22.1.1.10/16
    4. For tunnel management, configure the maximum number of times that the gateway will attempt to send signaling-request messages to a peer (SGSN or S-GW).
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set n3-requests 6
    5. For tunnel management, configure the time that the gateway waits before resending a signaling-request message when a response to the request has not been received.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set t3-response 8
    6. For path management, configure the maximum number of times that the gateway will attempt to send an echo-request message to a peer (SGSN or S-GW).
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set echo-n3-requests 6
    7. For path management, configure the time that the gateway waits before resending an echo-request message when an echo response to the echo request is not received.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set echo-t3-response 4
    8. For path management, configure the number of seconds that the gateway waits before sending an echo-request message after an echo response is received from the peer.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1]user@host# set echo-interval 65
    9. Configure the peer gateways to transport a 16-bit sequence number when GTP control packets are sent to and received from the peer gateways.
      [edit unified-edge mobile gateways ggsn-pgw MBG1 gtp peer-groups peer-grp-1 control]user@host# set sequence-number-length 16-bits
