[srslte-users] srsLTE 18.09 Release Announcement

[J Giovatto]

Hi,

Diagram attached.

Question are you enb, epc and mbms processes running in the same machine ?

If not you may need to set the M1 interfaces otherwise the defaults
should be fine.

m1u_multi_addr = 239.255.0.1
m1u_multi_if   = 10.99.3.1

BTW 239.255.0.1 is used for M1 IPC, not your dataplane routing.



The srs_mbms should create a tun interface,
something like this..

sgi_mb: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST>  mtu 1500
        inet 172.16.0.254  netmask 255.255.255.255  destination 172.16.0.254
        inet6 fe80::c93a:e0c2:6f70:677d  prefixlen 64  scopeid 0x20<link>
        unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 
txqueuelen 500  (UNSPEC)
        RX packets 0  bytes 0 (0.0 B)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 3  bytes 144 (144.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

you will need to direct your traffic to this interface for starters you
could use "ping -I sgi_mb 224.4.4.4" and watch the ue tun interface with
tcpdump etc.

required config changes:

ue.conf:
mbms_service  = 0

enb.conf:
sib_config = sib.mbsfn.conf
enable_mbsfn = true
