WRED monitors the shared buffer space utilization over a period of time.

WRED disables the TCP slow-start congestion control mechanism.

WRED uses two configurable slopes for each buffer pool: a high slope and a low slope.

WRED uses the shared buffer utilization, instead of the individual queue depth, to get a better picture of the average resource utilization of the shared buffer space.

WRED polices the shared buffer pool and marks all packets above a certain rate as "discard eligible."

A standalone policer has no parent arbiter, while a CFHP pohlicer has a parent arbiter.

A standalone policer has a fixed PIR rate, while a CFHP poker's PIR rate can be dynamically adjusted by its parent arbiter.

Both standalone and CFHP policers use the FIR bucket to gain access to their fair share of the available bandwidth.

Both standalone and CFHP policers use a policer output queue to store packets before they are forwarded.

In order to mark Layer 2 traffic, sgt-qos will set various ToS bits.

DSCP bits can be set per application, per routing instance.

The DSCP marking stays nc1 for all applications. Only the internal FC is manipulated across different applications.

In order to mark Layer 2 self-generated traffic, network interfaces must be set to dot1Q.

The internal forwarding class for self-generated traffic is set once and applied to the base router and all VPRN instances.

It will be queued in the reserved portion of the buffer pool and remain out-of-profile.

It will be queued in the reserved portion of the buffer pool if there are no in-profile packets already in the queue.

It will be queued in the reserved portion of the buffer pool and be in-profile.

It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.

It will be queued in the shared portion of the buffer pool but may be dropped if the buffer utilization exceeds the start-average value of the low slope.

PE2 pushes one label on the IP packet and forwards it to ASBR2.

ASBR2 forwards the IP packet with one label to ASBR1.

ASBR1 forwards the IP packet with two labels to PEL

PE1 forwards an unlabeled IP packet to CE1.

Router R1forms an iBGP session with router R2, and an eBGP session with router R3.

Router R1forms iBGP sessions with routers R2 and R3.

Router R1forms eBGP sessions with routers R2 and R3.

The types of BGP sessions with routers R2 and R3 cannot be determined.

Three primary paths,

Two primary paths and one backup path.

One primary path and two backup paths.

One primary path and one backup path.

The VPRN ID must match the value used in the vrf-target command.

The VPRN ID must match the value used in the route-distinguisher command.

The router-id command should not be used in this context.

The "no shutdown" command must be configured for the VPRN to be operationally UP.

The router will accept the update and send a notification.

The router will not accept the update and send a notification.

The router will accept the update and ignore the attribute.

The router will accept the update and propagate the attribute.
