-
DTE Interfaces
- Encapsulation per interface/per DLCI
- physical/logical
- multipoint/point-to-point
-
Interface Status
- Show interface
- Show frame PVC
- Backup interface
-
Encapsulation Types – Which method of specifying the upper layer protocol will be used?
- Cisco (default)
- IETF
- Type set on physical interface, or on end of interface-DLCI, or on end of map statement.
- Must match end-to-end in that non-Cisco routers (Juniper) use only IETF.
- Cisco routers will work even with mismatch, since the router does understand both.
-
Enabling CDP
- Disabled by default on frame relay interfaces
- Can be enabled per interface or sub-interface “cdp enable”
- Frame network will be transparent to cdp
- Enabling on physical does NOT enable it for sub-interfaces
-
-
-
Overview: purpose and operation
- Status information between Frame-Relay devices (UNI, NNI)
- Message types
- Status Enquiry sent by DTE
- Status Message Frame sent by DCE
- Update Status Message

- ansi (aka Annex-D)
- q933a (aka Annex-A)
- Differences
-
Configuration, Autosense
-

-
Number of PVCs limited by MTU.
-
-
-
Purpose, multipoint versus point-to-point
-

- Limitations
- Disabling
- Clear frame inarp
-
Static
- Local Address
-
Broadcast keyword
-
Map bridge / clns / IPv6
-
Show frame map
-
-
-
Topology
- TTL, Broadcast domain segmentation
- Mixing static and dynamic maps
- MTU Issues
- Controller MTU vs IP MTU
- Demo: ping with high MTU, 4000 byte packet from spoke to spoke with default mtu at hub. How get packet thru.
- Ping with df-bit set, demo “M” response. See debug ip icmp on hub.
-

-
Real life switching equipment
-
Lab:
- 2522, “virtual switch” with tunnel
- Set clock rate for back-to-back cables
-
Dedicated Frame-Relay switch
- Set LMI type (autosense only on DTE ints)
- Frame route statements
- Show frame route
-
Using the Connect syntax
-
Hybrid Switching (DCE-DTE)
- One side is interface type dce
- Same DLCI used in map statement on each side
- No frame route statements
- Could use interface-dlci on sub-interfaces, but intf-type always goes on major interface, not sub-interface!
- See Document ID 14194
-
Back-to-Back Switching (DTE-DTE)
- No frame switching or int type dce
- No Keepalive disables LMI for that interface
- Example uses interface-dlci with POINT-TO-POINT ints / could use maps.
- Inverse arp still operates: do not need lmi for inverse arp
- See Cisco Document ID 14193
-
Switching over a tunnel
- No frame config on tunnel
- Outside interfaces have frame route of incoming DLCI to tunnel DLCI. Tunnel DLCI is same on both sides
- Example shows route statements on a layer 3 DTE interface and on an interface configured as DCE
- See: “Switching over an IP Tunnel” in the WAN Configuration Guide for Frame Relay
- Completed “Virtual Switch” Example

STP Issues on multipoint
-
CDP Issues?

-
PPP over Frame-Relay
- Rfc 1973
- Offers authentication, no map requirement, POINT-TO-POINT interface for routing protocols.
- PPP over Frame Relay is supported only for serial interfaces.
- Supports only IP (not IPv6)
- Configure virtual-template interface
- Associate DLCI with virtual-template
- Note peer neighbor route
- Show int virtual-access 1 to see interface statistics
- Show frame pvc
- Show interface virtual-access
- DOiT Lab 8
- Debugging
-
MLPoFR for Voice over Frame Relay/ATM interworking
- Goal: reduce delay and jitter
- Enable queueing as desired and FRTS
- Create a virtual template and interface multilink
- Associate the VT with the bundle and the PVC
-
-
-
Useful when LMI is not end-to-end (no keepalive?)
-
Modes: bidirectional, request, reply, passive-reply
-
Required: set mode in map-class Frame-Relay
-
Configurable error threshold and event window
-
-
-
Configuration of target router No dhcp pool (broken?)
- ip helper
- bootp, not dhcp
- frame map

-
-
-
Traffic type on a PVC
- Priority-group
- LLQ
- Ip rtp priority
-
FR PIPQ
- Prioritize DLCIs. Ina map-class assign a DLCI High, Medium, Normal or Low
- At interface, assign priority queue limits
-
DLCI priority levels
- Different traffic types placed on different DLCIs, so different CIR for each type.
- Can use with custom or priority queueing to manage the bandwidth
- Permits multiple DLCIs on a point-to-point. Mapping provided by priority list.
-
Broadcast queue
- Broadcast queue has priority when transmitting below configured maximum. Maximum in bps and packets/sec. No more than the maximum is provided. A policed priority queue for broadcast traffic.
- When configured, debug frame packet says “broadcast dequeue” for each RIP V2 packet. So includes multicast.
- Show interface shows broadcast queue.
- Test: with frame-relay broadcast-queue 200 1000 1 extended ping to 224.1.1.1 with zero timeout filled queue and then doled out the pings. Can also ping 172.16.14.255 to fill queue.
- Buffers traffic replicated for multiple DLCIs, not original packet, which goes through normal queue.
- Sh int shows number of packets in queue, number dropped and original number
-
-
-
Traffic policing on the Frame-Relay switched interface
- Map-class to set CIR, Bc and Be
- All must be set
- Up to CIR transmitted, between CIR and EIR set DE, over EIR drop
- Apply to interface or PVC
- Activate Frame-Relay policing
-
Frame-Relay congestion management (switched)
- Can drop traffic marked DE when threshold percent of queue depth is reached
- Can set FECN and BECN bits when ECN queue depth percent is reached.
