Hi Xander,
Is 9001-LC a SE or TR?
What is the TCAM size of ASR 9001? How many ACLs in 9001? Does 9001 supports object group for creating ACL?
Warm Regards

Hi,
In XR, how can we enable IPSLA to see the MOS value in UDP jitter. Does the Group scheduling is supported for UDP jitter?
Warm regards.

Hi,
There is an indirect connectivity between ASR 903 router and Cisco 3560CG router for which the configured to be in same IP segment. The two devices are not pinging from each other, but able to ping other devices from both which are in the same LAN segment.
Router:
-----------
interface Po4
service instance 600 ethernet description COLLECTOR encapsulation dot1q 600 rewrite ingress tag pop 1 symmetric bridge-domain 600
interface BDI600 description COLLECTOR ip address 100.66.44.9 255.255.254.0 no ip redirects no ip unreachables

Switch:
-----------

Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 100.66.44.9, timeout is 2 seconds: ..... Success rate is 0 percent (0/5)
3560CG#sh ip arp | i 100.66.44.9 Internet 100.66.44.9 0 188b.454c.5cbf ARPA Vlan600
One thing is in arp table of the switch, arp for that particular router is continuously flushing and always is "0". On the other end, in router there is
no problem, the arp for the switch is aging.
Warm Regards.

Hi,
Yes the version is 6.1.2. Using the "xrv9k-fullk9-x.vrr.vga-6.1.2.ova" image for testing.
The logs appears and stops suddenly, couldnt correlate with anything since no neighbors are established.

Hello Folks,
Trying to know if the BFD running over OSPF can detect the physical and line protocol up and bring up the OSPF immediately instead of using OSPF hello for link availability detection.
Ran a test in lab with ASR 9006 and ASR 9001 connected back to back and configured with BFD (async w/o echo, 100msX3) over OSPF (default timers). Finding the interface comes up initiates OSPF to come up and then the BFD session is created.
The aim of the exercise to be make the OSPF up immediately without any delay once the physical link comes up. Since the OSPF fast hello is not supported, trying to site BFD's hello if it can help.
Below is the log captured while the link comes up.

Hi Xander,
There is no problem when the active link goes down, the standby links takes over immediately and there is no be down.
Yes as you mentioned, the be goes down when link with low priority(in value) comes back to up, eventually the protocols are going down
Here's what I find in the router:
