Passport L2 Switching
• HA Mode
Outer Switches dual-homed
using standard link
aggregation protocols.
– CPU mirroring ensures zero
impact failure
• Distributed MLT
– Link aggregation over multiple
modules removes single point of
failure.
Two Passport
8600s share
forwarding tables
and act as one
through the IST.
• Split-MLT
– Link aggregation used for network
resiliency
– Two switches act as one
– All links active and passing traffic
– No need for the additional
complexity of multiple VLANs
“Split-MLT is the only mechanism
that will protect sensitive
applications like VOIP from
network outages.”

Passport L3 Routing
A Single Gateway address is
now balanced across both
Passport 8600s.
• Routing Protocol Support
– RIP1,2, OSPF and BGP4
• VRRP Backup-Master
– Simplifies network configuration
– Better network utilization
Backup-Master
allows an 8600
that is in backup
mode to route
traffic
• VRRP fast interval timers
– Faster VRRP fail-over
– Sub-second to match Split-MLT
• IP and IPX routing policies
– Improved control of routes
– Increase security and control.
“Backup-Master simplifies network
design by balancing traffic and
reducing the number of
subnets/DHCP scopes.”

Passport Multicast
• Passport 8600 shared
memory architecture is the
basis of unequalled
Multicast scaling and
performance.
• PIM-SSM allows source
specific multicast trees to
be created, essential in
mass multimedia (TV)
applications.
• Fast join and leave
capability improves stream
setup time and reduces
bandwidth.
Shared memory
architecture
delivers superior
multicast
performance
PIM-SSM acts like
a static route for
multicast.
Fast join and leave allows selection of
multicast stream just like TV channel
hopping

L3 Routing
At layer 2 these extra links need to
be blocked to prevent network
loops. This is usually implemented
using a protocol called spanning
tree (802.1d)
Spanning tree protocol prevents
these loops by deciding the best
links to use and blocking all the rest.
Basically you’re paying for stuff you
can’t use !
NORTEL NETWORKS CONFIDENTIAL
Presentation Name - 23
Spanning Tree Features
• Spanning Tree Protocol (STP)
–
–
–
–
–
Provides redundant paths and detects loops in L2 networks
Redundant links are activated after failure
Redundant links are not utilized for data traffic
Slow network convergence - minimum of 30 seconds
Fast L3 redundant protocols like VRRP and OSPF depend on slow STP
convergence
• Spanning Tree Protocol - Proprietary Hacks and Fixes
– Uplink Fast, Port Fast, Fast Start
– Improves convergence time by 15-30 seconds
– Bandwidth is still wasted by blocked ports
• 802.1w Rapid Spanning Tree Protocol
– Faster convergence, 5 seconds on failure
– Same re-convergence, 30 seconds plus on repair
– Same restriction on redundant links
Spanning Tree will not protect applications

S-MLT Link Aggregation
Our Fresh approach to the
spanning tree problem
“Extends
reliability
benefits to
attached 3rd
party switches
through
802.3AD link
aggregation”
• Description
– Split MLT makes the two core switches act as
one at Layer 2
– Standard Link aggregation protocols used for
network resiliency as well as bandwidth
– Both Links are active, appear as one, with
traffic balanced across all available links.
• Advantages
–
–
–
–
–
Less complex than spanning tree
Better bandwidth utilization
Faster Fail-over and recovery
Protects applications from outages
In service hitless upgrades
“Maintains state of voice and video sessions
through fail-over”

• New multimedia applications require more bandwidth
– Multi channel Gigabit metro solution is the answer, but…
– Normally this would require
•
•
Multiple expensive leased fiber runs for resilience or
Expensive and complex DWDM equipment to reduce fibers
