Scope

• This MIB structure contains configuration which
  is limited to the objects required for
  configuring VPLS as described in
• draft-ietf-l2vpn-ldp-09.txt

4
Brief overview of Tables

• vplsConfigTable
• Definition for VPLS-wide parameters
• vplsPwBindTable
• Definition for per Pseudowire configuration

5
MIB Module Architecture
6
MIB Usage

• To configure a VPLS service the following tables
  need to be configured
• vplsConfigTable
• Index vplsIndex
• pwTable PWE3-PW-MIB
• Index pwIndex
• vplsPwBindTable
• Index vplsIndex, vplsPwIndex

7
Future Enhancements

• Known issues/ unresolved issues
• Where to store the MAC Address and its related
  information. BRIDGE-MIB or within the VPLS MIB
• Constraint is qualified/unqualified learning
• Notion of qualified and unqualified learning in
  absent
• VPLS MTU is missing
• This is needed despite PW MTU since we need to
  have a service wide MTU.
• vplsMacLearning is a redundant object
• vplsDiscardUnknownDest is non required object
• vplsMacAgingTimer is absent

8
Future Enhancements

• vplsMacAddrLimit is absent
• Number of learnt Mac Addresses is absent
• Multicast frame handling is absent
• Broadcast
• IGMP Snoop
• PIM Snoop
• VPLS notion not supported yet.
• Change needed in PWE-3 MIB so that a PW can
  terminate on either an Attachment Circuit or a
  VSI.
• Provisioning a Pseudo Wire as Primary or
  Standby is absent

9
Future Enhancements

• vplsPwBindTable
• Type of bind (spoke / mesh) is absent
• MacAddrLimit may be per VPLS, not per PW. We may
  remove this object.
• Merge with VPWS/ IPLS MIBs ?
