undo aggregate address mask [ as-set | attribute-policy route-policy-name |detail-suppressed | origin-policy route-policy-name | suppress-policy route-policy-name ] *

View

IPv4 multicast sub-address family view

Parameters

address : Address of the aggregated route.

mask : Network mask of the aggregated route.

as-set : Generates a route with AS_SET segment. This parameter is not recommendedwhen aggregating many AS paths.

attribute-policy route-policy-name : Sets aggregate attribute.

detail-suppressed : Advertises the aggregated routes rather than the specific routes.

origin-policy route-policy-name : Filters the originate routes of the aggregate.

suppress-policy route-policy-name : Does not advertise the specific routes selected.

Description

Use the aggregate command to create a multicast aggregated record in the BGProuting table.

Use the undo aggregate command to disable this function.

By default, no route is aggregated.

Use the aggregate command without parameters to create one local aggregated routeand set atomic aggregation attributes.

1.1.5 default med

Syntax

default med med-value

undo default med

View


Parameters

med-value : MED value, in the range of 0 to 4294967295. By default, it is 0.

DescriptionUse the default med command to configure system MED value.

Use the display bgp multicast group command to restore the default value.

Multi-exit discriminator (MED) attribute is the external metric for a route. Unlike localprecedence attribute, MED is exchanged, between ASs, and one it enters an AS, itdoes not leave the AS. MED attribute is used in best route selection. When a devicerunning BGP travels through different external peers and get the routes with identicaldestination, but different next-hop addresses, it selects these routes according to theirMED values. The route with smaller MED value will be selected as the external AS

route if other attributes are the same.

Examples

# Configure system MED value as 25.

connection will be retained.If idle-forever is provided, a warning message is generated when the number of routesreceived by the specified peer group reaches the allowed maximum number and at thesame time the BGP connection is removed. The connection can be re-established onlyby means of the reset bgp command.

If idle-timeout is provided, a warning message is generated when the number of routesreceived by the specified peer group reaches the allowed maximum number, and theBGP connection is torn down at the same time. The period specified by timeout-value must pass before the connection can be re-established.

Examples

# Set the maximum number of routes that can be received by each outgoing peer in thepeer group to 20000, with the following actions:

A warning message is displayed when the number of received routes exceeds4000;

When the number of received routes exceeds 20000, the connection is removed; The BGP connection is re-established 30 seconds later.

Parameters

ebgp-value : EBGP route priority, in the range of 1 to 256. By default, it is 256.

ibgp-value : IBGP route priority, in the range of 1 to 256. By default, it is 256.

local-value : Local route priority, in the range of 1 to 256. By default, it is 130.

Description

Use the preference command to configure MBGP protocol priority.

Use the undo preference command to restore the default priority.

You can configure different priority values for different types of MBGP routes.

Parameters

None

Description

Use the reflect between-clients command to enable route reflection between clients.Use the undo reflect between-clients command to disable route reflection betweenclients.

When configured, the route reflector can reflect routes of a client to other clients.

By default, all-connection is not required for the clients with route reflectors configured,since the routes are by default reflected from one client to others. For all-connectionclients, route reflection is unnecessary.

Related commands: reflector cluster-id , peer reflect-client .

Parameters

cluster-id : Route reflector cluster ID, in integer number or IP address format, range 1 to4294967295.

address : Route reflector cluster ID in IP address format.

Description

Use the reflector cluster-id command to configure route reflector cluster ID.

Use the undo reflector cluster-id command to delete route reflector cluster ID.

By default, each route reflector uses its own route ID as cluster ID.

In general, one cluster has only one route reflector, and then the router ID for the routereflector can be used to identify the cluster. If a cluster has several route reflectors, formultiple route reflectors can improve network stability, then you can use this commandto specify the same cluster ID for them all.

Parameters

None

Description

Use the summary command to set to auto-aggregate subnet routes.

Use the undo summary command to remove the configuration.

By default, subnet routes cannot be aggregated automatically.
