Inter-VLAN Router

VLANs in a Cisco network enable network managers to group

users logically rather than by physical location—easing adds,

moves,andchanges. The high-performanceCisco 3600routing

engine combined with the feature-rich Fast Ethernet network

module makes an ideal solution for a low-density,

high-performance inter-VLAN routing. The Cisco 3600 routes

between VLANs resident in Cisco Catalyst

series switches

with Cisco IOS Inter-Switch Link (ISL) protocol on the Fast

Ethernet network module.

Voice Integration

The Cisco 3600 supports Voice over IP (VoIP) and Voice over

Frame Relay (VoFR)which allows voice traffic to betransported

over existing WAN infrastructures including ISDN, leased line,

ATM, and Frame Relay.

This solution gives you the opportunity to save

long-distance tariffs normally incurred using the Public

Switched TelephoneNetwork (PSTN) while providing both the

quality and reliability you expect from your telephone service.

Additional features include support for fax relay and

interoperability with other H.323 applications.

Bandwidth efﬁciencies include:

• Voice compression using standard compression techniques

such as G.729

• Silence suppression

• Resource Reservation Protocol (RSVP), Weighted Fair

Queuing (WFQ), multilink fragmentation and interleave
