Juniper JUNOSE 11.1.X MULTICAST ROUTING, Configuration Manual

Page: 61 / 270

■
Use to display the mroute port outgoing interface, limits, counts, bandwidth
settings, and bandwidth accepted.
NOTE: This command displays information for mroutes on a port across all virtual
routers.
■
Field descriptions
■
Port—Slot/port value on the router
■
Limit—Port limit value defined for the specified port; -l indicates that no
mrout port limits have been configured for the port
■
Count—Number of mroute outgoing interfaces on the specified port
■
BW bps—Bandwidth limit, in bits per second
■
Priority BW bps—Priority bandwidth limit, in bits per second
■
Admitted—Bandwidth admitted on the port, in bits per second
■
Example

Support for Multicast Router Information
When you enable multicast routing on a virtual router, the router acts as a multicast
router information (mrinfo) server. This feature enables the router to respond to
mrinfo requests from other network hosts. Specifically, E Series virtual routers respond
to DVMRP ask neighbors and DVMRP ask neighbors2 requests.
Each virtual router responds to mrinfo requests with a list of multicast interfaces and
their IP addresses. If appropriate, the virtual router also supplies the following
information for each interface:
■
Current functional status of the interface (for example, if the interface is down).
■
Information as to whether the interface is disabled and the reason for the interface
being disabled—either because IP is not configured on the interface or because
the interface has been disabled through the software.
■
Whether the interface is performing the IGMP queries for this subnet.
■
Information about PIM neighbors:
