  • Page 23: Mpls

    MPLS is not enabled by default and must be explicitly enabled. MPLS is independent of any routing protocol but is considered multiprotocol because it works with the Internet Protocol (IP) and frame relay network protocols. 7450 ESS MPLS Guide Page 23...

  • Page 24: Mpls Label Stack

    Service (CoS). This bit is set to 1 for the last entry (bottom) in the label stack, and 0 for all other label stack entries. This 8-bit field is used to encode a TTL value. Page 24 7450 ESS MPLS Guide...

  • Page 25: Figure 2: Label Packet Placement

    Labeled packet processing is independent of the level of hierarchy. Processing is always based on the top label in the stack which includes information about the operations to perform on the packet's label stack. 7450 ESS MPLS Guide Page 25...

  • Page 26: Label Values

    RSVP, LDP, and BGP control planes for both MPLS LSP and service labels. • Label values 262,144 (131,072 in chassis modes lower than D) through 1,048,575 are reserved for future use. Page 26 7450 ESS MPLS Guide...

  • Page 27: Label Switching Routers

    → Explicit-path LSPs — MPLS uses RSVP-TE to set up explicit path LSPs. The hops within the LSP are configured manually. The intermediate hops must be configured as either strict or loose meaning that the LSP must take either a direct path from the 7450 ESS MPLS Guide Page 27...
  • Page 28 An LSP is not set up if the hop limit is exceeded. The hop count is set to 255 by default for the primary and secondary paths. It is set to 16 by default for a bypass or detour LSP path. Page 28 7450 ESS MPLS Guide...

  • Page 29: Mpls Facility Bypass Method Of Mpls Fast Re-Route (Frr)

    LSP in the default behavior. Users can disable the dynamic bypass creation on a per node basis using the CLI. A maximum of 1000 associations of primary LSP paths can be made with a single manual bypass by default. The max-bypass-associations integer command increases the number of associations. 7450 ESS MPLS Guide Page 29...

  • Page 30: Figure 3: Bypass Tunnel Nodes

    Step 3, the MPLS/RSVP task will repeat Steps 1-3 looking for a suitable link-protect bypass LSP. If none are found, the primary LSP will have no protection and the PLR node must clear the “local protection available” flag in the IPv4 Page 30 7450 ESS MPLS Guide...
  • Page 31 Similarly, if an LSP is signaled while the manual bypass is in the down state, the node will only signal a dynamic bypass tunnel if the user has not disabled dynamic tunnels. 7450 ESS MPLS Guide Page 31...

  • Page 32: Figure 4: Frr Node-Protection Example

    Once P_4 is back online and such a path is available, A new bypass tunnel will be signalled and LSP 1 will get associated with this new bypass tunnel. Page 32 7450 ESS MPLS Guide...

  • Page 33: Uniform Frr Failover Time

    Adding auto-bandwidth at the LSP level starts the measurement of LSP bandwidth described in Measurement of LSP Bandwidth on page 36 and allows auto-bandwidth adjustments to take place based on the triggers described in Periodic Automatic Bandwidth Adjustment on page 7450 ESS MPLS Guide Page 33...
  • Page 34 • operational BW: the last known reserved BW for a given path, as recorded in the MIB • configured BW: the bandwidth explicitly configured for the LSP path by the user in CLI Page 34 7450 ESS MPLS Guide...
  • Page 35 If the primary path is not the currently active path and it has not gone down, then any MB uses the configured BW for the primary path. However, if the configured BW is changed for a path that is currently not active, then a config change MBB is not triggered. 7450 ESS MPLS Guide Page 35...
  • Page 36 Automatic adjustment of RSVP LSP bandwidth based on measured traffic rate into the tunnel requires the LSP to be configured for egress statistics collection at the ingress LER. The following CLI shows an example: config router mpls lsp name egress-statistics accounting-policy 99 collect-stats no shutdown exit Page 36 7450 ESS MPLS Guide...
  • Page 37 288, which means the default adjust interval is 86400 seconds or 24 hours. The system enforces the restriction that adjust-multiplier is equal to or greater than sample-multiplier. It is recommended that the adjust-multiplier be an integer multiple of the sample-multiplier. 7450 ESS MPLS Guide Page 37...
  • Page 38 — The bandwidth that is provided to the CSPF algorithm and signaled in the SENDER_TSPEC and FLOWSPEC objects when an auto-bandwidth adjustment is attempted. • min — The configured min-bandwidth of the LSP. Page 38 7450 ESS MPLS Guide...
  • Page 39 For cases where the measured bandwidth of an LSP has increased significantly since the start of the current adjust interval it may be desirable for the system to preemptively adjust the bandwidth of the LSP and not wait until the end of the adjust interval. 7450 ESS MPLS Guide Page 39...
  • Page 40 [lsp lsp-name [force [bandwidth mbps]]] command to attempt immediate auto-bandwidth adjustment for either one specific LSP or all active LSPs. If the LSP is not specified then the system assumes the command applies to all LSPs. Page 40 7450 ESS MPLS Guide...
  • Page 41 The adjust-interval, maximum average data rate and overflow count are not reset by the manual auto-bandwidth command, whether or not the bandwidth adjustment succeeds or fails. The overflow count is reset only if the manual auto-bandwidth adjustment is successful. 7450 ESS MPLS Guide Page 41...

  • Page 42: Rsvp

    The ELER sends label binding information in the RESV messages in response to PATH messages received. • The LSP is considered operational when the ILER receives the label binding information. PATH PATH PATH ILER ELER RESV RESV RESV OSSG015 Figure 5: Establishing LSPs Page 42 7450 ESS MPLS Guide...

    ILER, in a direction opposite to that followed by the path message. Each LSR that processes the RESV message carrying a label object uses the received label for outgoing traffic associated with the specific LSP. When the RESV message arrives at the ingress LSR, the LSP is established. 7450 ESS MPLS Guide Page 43...

  • Page 44: Using Rsvp For Mpls

    The Hello protocol extension is composed of a hello message, a hello request object and a hello ACK object. Hello processing between two neighbors supports independent selection of failure detection intervals. Each neighbor can automatically issue hello request objects. Each hello request object is answered by a hello ACK object. Page 44 7450 ESS MPLS Guide...

  • Page 45: Md5 Authentication Of Rsvp Interface

    Within RSVP, authentication must be explicitly configured through the use of the authentication keychain mechanism.

    LDP session is to be set up or torn down, and when labels are to be exchanged or withdrawn. In turn, LDP informs service manager of relevant LDP events, such as connection setups and failures, timeouts, labels signaled/withdrawn. 7450 ESS MPLS Guide Page 523...

  • Page 524: Execution Flow

    In order for a targeted LDP (T-LDP) session to be established, an adjacency must be created. The LDP extended discovery mechanism requires hello messages to be exchanged between two peers for session establishment. After the adjacency establishment, session setup is attempted.
