Examples
•
On multi-core devices:
# Enable IPv6 MFIB packet debugging. When IPv6 PIM-DM is enabled , output similar to the
following example is generated:
<Sysname> debugging mfib ipv6 packet
*Apr 26 12:11:42:03 2008 Sysname DP_MFIB/7/PACKET:
(IPv6 0): (40::2, FF1E::101:101) Receive packet from interface Ethernet1/1 in vcpu
7. (D46144)
// The IPv6 MFIB received a multicast packet (40::2, FF1E::101:101) from Ethernet 1/1 on VCPU
7.
*Apr 26 12:11:42:03 2008 Sysname DP_MFIB/7/PACKET:
(IPv6 0): (40::2, FF1E::101:101) Search entry in DP MFIB. (D46196)
// The IPv6 MFIB searched the data plane for the forwarding entry for the multicast packet (40::2,
FF1E::101:101).
*Apr 26 12:11:42:05 2008 Sysname DP_MFIB/7/PACKET:
(IPv6 0): (40::2, FF1E::101:101) Send packet to control plane. (D46218)
// The data plane sent a IPv6 multicast packet (40::2, FF1E::101:101) to the control plane.
*Apr 26 12:11:42:05 2008 Sysname MFIB/7/MFIB PACKET:
IPv6 (public net): Receive packet (40::2, FF1E::101:101), iif = Ethernet1/1, TTL =
128(A162367)
// IPv6 multicast data (40::2, FF1E::101:101) with the TTL value of 128 was received on Ethernet
1/1.
*Apr 26 12:11:42:06 2008 Sysname MFIB/7/MFIB PACKET:
IPv6 (public net): No MFIB entry matches (40::2, FF1E::101:101)(A162463)
// No matching IPv6 multicast forwarding entry for the packet (40::2, FF1E::101:101) was
found.
*Apr 26 12:11:42:30 2008 Sysname MFIB/7/MFIB PACKET:
IPv6 (public net): Cache the packet for (40::2, FF1E::101:101)(A081612)
// The MFIB cached the multicast packet (40::2, FF1E::101:101).
# Enable IPv6 MFIB route debugging. When IPv6 PIM-DM is enabled on interfaces, output similar
to the following example is generated:
<Sysname> debugging mfib ipv6 route
*Apr 26 12:17:11:56 2008 Sysname MFIB/7/MFIB ROUTE:
IPv6 (public net): Receive no cache report,add dummy entry (40::2,
FF1E::101:101)(A07107)
*Apr 26 12:17:11:56 2008 Sysname MFIB/7/MFIB ROUTE:
IPv6 (public net): Entry (40::2, FF1E::101:101) is added to dummy list(A064210)
*Apr 26 12:17:11:57 2008 Sysname MFIB/7/MFIB ROUTE:
IPv6 (public net): The Dummy entry (40::2, FF1E::101:101) is added(A062057)
// The control plane has received the IPv6 multicast packet (40::2, FF1E::101:101). No
forwarding entry for the packet was found. The control plane created a dummy entry for it.
*Apr 26 12:17:11:57 2008 Sysname DP_MFIB/7/ROUTE:
(IPv6 0): (40::2, FF1E::101:101) Add entry successfully! (D44177)
