Ephemeral (MOTL) MOs for URIB

The following table lists the queries for retrieving route information through ephemeral MOs. These were added in Release 9.3(1).

Show Command	Ephemeral DN Query
`show ip route vrf all`	`http://<mgmt0_IP>/api/node/mo/sys/urib.json?rsp-foreign-subtree=ephemeral`
`show ipv6 route vrf all`	`http://<mgmt0_IP>/api/node/mo/sys/u6rib.json?rsp-foreign-subtree=ephemeral`
`show ip route vrf vrfname`	`http://<mgmt0_IP>/api/node/mo/sys/urib/table4-vrfname.json?rsp-foreign-subtree=ephemeral`
`show ipv6 route vrf vrfname`	`http://<mgmt0_IP>/api/node/mo/sys/u6rib/table6-vrfname.json?rsp-foreign-subtree=ephemeral`
`show routing summary vrf all`	`http://<mgmt0_IP>/api/node/mo/sys/urib.json?rsp-foreign-subtree=ephemeral&batch-context=summary`
`show routing ipv6 summary vrf all`	`http://<mgmt0_IP>/api/node/mo/sys/u6rib.json?rsp-foreign-subtree=ephemeral&batch-context=summary`
`show routing summary vrf vrfname`	`http://<mgmt0_IP>/api/node/mo/sys/urib/table4-vrfname.json?rsp-foreign-subtree=ephemeral&batch-context=summary`
`show routing ipv6 summary vrf vrfname`	`http://<mgmt0_IP>/api/node/mo/sys/u6rib/table6-vrfname.json?rsp-foreign-subtree=ephemeral&batch-context=summary`

Batch Context

Use batch context tags in the table below to filter the queries. The format is a list of single tag or property:values pairs separated by a semi colon. For example: ";;:;;:;…"

Tag	Description
summary	Adds the summary MO to the output
uni	Shows the unicast paths. Note: Uni is always implied if neither uni or multi is specified.
multi	Show the multicast paths. Note: If only multi is specified, unicast paths are not given. To get both unicast and multicast, both uni and multi must be used.
backup	Shows the best and backup paths. Note: By default, only the best paths are given.
no-nh	Do not fill the next-hop MO.
detail	Dump detailed information about the next hops. See notes below.
noroutes	Do not dump the routes, only the summary.

Notes: If no tags are used, the default is to show only the unicast path. Next-hop detailed information includes:

Labels related information
Client data pointer
BGP Origin/Peer
RNH information
Tlv information
Extended community
Attached export information

Property	Value
rt	An address string parse-able by inet_pton. The mask (optional) is specified by adding an ‘_’ after the address: e.g. 30.4.1.0_24 or 100::_16 If no mask is specified, the default is 32 for urib and 128 for u6rib. Note: You can use the rt property to see only one route. Also, you can specify the property only once in the batch-context. If the property is not used, the full table is given.
client	A list of clients separated by coma. For example: “static,broadcast,local”. This will show only the routes where at least one of these clients has paths.
