Chapter 1 Interface Gigabit Ethernet Interfaces No interoperability configurations required between the platforms 10GE ports on CISCO ME3600X/3800X operating at 1Gig rate On CISCO ME3600X/3800X the TenGig Ethernet ports can operate at 1 Gig when 1 Gig SFPs are plugged in. In such scenarios additional interoperability commands are required. Auto negotiation is disabled by default on Gigabit Ethernet Interfaces in CISCO ASR 9000.

Chapter 5 VPWS CISCO ASR 9000 EFP MTU behaviour • CISCO ASR 9000 INTELLIGENTLY adjusts sub-interface/EFP MTU • If “rewrite pop” is configured, MTU size is reduced by the 4 bytes for each VLAN popped. • If “rewrite push” is configured, MTU size is increased by 4 bytes. PROBLEM : The VPWS will not come up due to MTU mismatch ! SOLUTION : Configure MTU manually on the EFP on CISCO ASR 9000 to match with the MTU size on the remote side ! NOTE : Remember CISCO ASR 9000 takes L2 size on the MTU command.

Chapter 7 VPLS using BGP auto discovery VPLS CLI and implementational differences There is a distinct difference as how the split horizon groups are implemented in ME/CISCO ASR 903 platforms and CISCO ASR 9000. This is important to understand while configuring HVPLS or E-TREE based deployment scenario. CISCO ME3600X/3800X and CISCO ASR 903 CISCO ASR 9000 1.
0 to 2. So in a E-Tree based deployment all the root EFPs are put in one split-horizon group and the Root is put in another split-horizon group. So all the leafs communicate with Root and not with each other. The option “split-horizon group” enables splithorizon on EFPs. The concept of split-horizon groups are a different in CISCO ASR 9000. § 3 Split Horizon groups are defined in CISCO ASR 9000 § Group 0 is default.

Chapter 9 Layer 2 Control Protocol Forwarding The Layer 2 Control Protocol forwarding bahaviors are different between the set of CISCO ASR 9000 and ME and ASR platforms. CISCO ME3600X/3800X and CISCO ASR 903 behaviour and configuration • By default all layer 2 control frames are dropped on the EFP. • The layer 2 control protocol forwarding is enabled using the command “l2protocol forward” • By enabling just the command “ l2protocol forwarding” All layer 2 control protocols will be forwarded.
CISCO ASR 9000 behaviour and configuration • On the CISCO ASR 9000 all the L2 control frames are forwarded by default on the EFP. • In order to block or permit a certain set of protocols. The L2 access lists need to be configured.
