Juniper chapter 7 : services
Thursday, August 6, 2009
*** These are the core points from the student guide with some modifications if possible
Chapter objectives :
-> service architectures
-> mlppp
-> nat/pat
layer 2 services include
MLPPP -> multilink point-to-point
MLFR -> multilink frame-relay
CRTP -> compressed real-time protocol
layer 3 services
AS pic (BUZZ WORD)
-> Provides services through service sets and its adaptive services interfaces (sp-)
-> stateful firewalls , nat , ipsec vpn , ids can be provided by as pic
Service Interfaces:
Different services are provided by different Pics
-> AS pic : AS pic supports all services
-> ASM is an optional component that you can order with the M7I router
-> J-series router
-> Has software processes that support the same services as the AS pic
-> Interface on J-series router will be designated as ls- rather than lsq-
-> Link services pic
-> Provides MLPPP and MLFR support and designated as ls- similar to j-series
-> Tunnel services
-> gre , ip-in-ip
-> Multiservice Pic and AS pic service
-> Multiservice pic or as pic should be configured so that they provide Layer 2 or Layer 3 but not both
-> as pic defaults to settings of Layer 3
"show chassis hardware" -> to determine the service-package
